The Mahdi features in both ] and ] ], though they differ extensively on his attributes and status. Among ], the Mahdi is believed to be ] ], twelfth Imam, son of the eleventh Imam, ] ({{Died in|874}}), who is said to be in ] ({{Transliteration|ar|ghayba}}) by divine will. This is rejected by Sunnis, who assert that the Mahdi has not been born yet. | |||
There are two ] of the zebra finch: | |||
* ''Taeniopygia guttata guttata'', the Timor zebra finch, extends from ] in the ] or ] in ] to Sermata, in addition to coastal areas around the continent of Australia. | |||
* '']'' is found over the wide range of continental Australia; it is sometimes split as the Australian zebra finch.<ref name="hbwc"/> | |||
==Etymology== | |||
The term ''Mahdi'' is derived from the Arabic root ''h-d-y'' ({{lang|ar|ه-د-ي}}), commonly used to mean "divine guidance".{{sfn|Madelung|1986|p=1231}} Although the root appears in the ] at multiple places and in various contexts, the word ''Mahdi'' never occurs in the book.{{sfn|Arjomand|2007|pp=134–136}} The associated verb is ''hada'', which means to guide. However, ''Mahdi'' can be read in active voice, where it means the one who guides, as well as passive voice, where it means the one who is guided.{{sfn | Cook | 2002a | pp=138–139}} | |||
==Historical development== | |||
The zebra finch likely evolved in Australia, with either northern or southeastern Australia postulated as two places where the genus arose. The present-day distribution of the subspecies ''T. g. guttata'' is likely due to a Pleistocene glaciation event where the sea level dropped between about {{convert|100|and|150|m|ft}}, putting the coasts of Timor and Australia closer. This allowed birds swept out to sea by cyclones to see mountains near the west coast of Timor, which prompted them to make landfall on the island.<ref name="Zann9–10">{{harvnb|Zann|1996|pp=9–10}}</ref> | |||
===Pre-Islamic ideas=== | |||
Some historians suggest that the term itself was probably introduced into Islam by southern Arabian tribes who had settled in ] in the mid-7th century. They believed that the Mahdi would lead them back to their homeland and re-establish the ]. They also believed that he would eventually conquer ].{{sfn|Arjomand|2007|pp=134–136}} It has also been suggested that the concept of the Mahdi may have been derived from earlier messianic ] and ] beliefs.<ref name=etan/>{{Sfn|Arjomand|2000}} Accordingly, traditions were introduced to support certain political interests, especially anti-Abbasid sentiments.{{Sfn|Arjomand|2000}} These traditions about the Mahdi appeared only at later times in ] such as ''{{Transliteration|ar|]}} and {{Transliteration|ar|]}}'', but are absent from the early works of ] and ].<ref name=Glasse/> | |||
===Origin=== | |||
The ] differences between the subspecies include differences in size. ''T. g. guttata'' is smaller than ''T. g. castanotis''. In addition, the ''T. g. guttata'' males do not have the fine barring found on the throat and upper breast and have smaller breast bands.<ref name="hbwg"/> | |||
The term ''al-Mahdi'' was employed from the beginning of Islam, but only as an honorific epithet ("the guide") and without any messianic significance. As an honorific, it was used in some instances to describe Muhammad (by ]), ], al-Husayn, and various ] ({{Lang|ar|هداة مهديون}}, {{transliteration|ar|hudat mahdiyyun}}). During the ] (680–692), after the death of ] ({{Reign|661|680}}), the term acquired a new meaning of a ruler who would restore Islam to its perfect form and restore justice after oppression. ], who laid claim to the caliphate against the Umayyads and found temporary success during the civil war, presented himself in this role. Although the title Mahdi was not applied to him, his career as the anti-caliph significantly influenced the future development of the concept.{{sfn|Madelung|1986|p=1231}} A hadith was promulgated in which Muhammad prophesies the coming of a just ruler.{{sfn|Madelung|1981|pp=292ff}}{{efn|D. S. Atema first dated this hadith to between Yazid's death and Ibn al-Zubayr's death. ] narrowed this down to 684, just after the death of Yazid.{{sfn|Madelung|1981|pp=292ff}} ] and ] have contested Madelung's dating. It is nevertheless generally accepted that the hadith is patterned on Ibn al-Zubayr's career.{{sfn|Cook|2016|pp=230–232}}{{sfn|Cook|2002a|p=155}} David Cook further states that the latter part of the hadith is totally legendary and is unrelated to Ibn al-Zubayr.{{sfn|Cook|2002a|p=155}}}} {{blockquote|There will arise a difference after the death of a caliph, and a man of the people of Medina will go forth fleeing to Mecca. Then some of the people of Mecca will come to him and will make him rise in revolt against his will ... An expedition will be sent against him from Syria but will be swallowed up ... in the desert between Mecca and Medina. When the people see this, the righteous men ... of Syria and ... Iraq will come to him and pledge allegiance to him. Thereafter a man of the Quraysh will arise whose maternal uncles are of Kalb. He will send an expedition against them, but they will defeat them ... He will then divide the wealth and act among them according to the Sunna of their Prophet. Islam will settle down firmly on the ground ... He will stay seven years and then die, and the Muslims will pray over him.{{sfn|Madelung|1981|p=291}}}} Refusing to recognize the new caliph, ] ({{Reign|680|683}}), after Mu'awiya's death in 680, Ibn al-Zubayr had fled to the Meccan sanctuary. From there he launched anti-Umayyad propaganda, calling for a {{transliteration|ar|shura}} of the Quraysh to elect a new caliph. Those opposed to the Umayyads were paying him homage and asking for the public proclamation of his caliphate, forcing Yazid to send an army to dislodge him in 683. After defeating rebels in the nearby ], the army besieged Mecca but was forced to withdraw as a result of Yazid's sudden death shortly afterward. Ibn al-Zubayr was recognized caliph in Arabia, Iraq, and parts of Syria, where Yazid's son and successor ] ({{Reign|683|684}}) held power in Damascus and adjoining areas. The hadith hoped to enlist support against an expected Umayyad campaign from Syria. The Umayyads did indeed send another army to Mecca in 692, but contrary to the hadith's prediction was successful in removing Ibn al-Zubayr. The hadith lost relevance soon afterward, but resurfaced in the ]n hadith circles a generation later, this time removed from its original context and understood as referring to a future restorer.{{sfn|Madelung|1981|pp=292ff}}{{sfn|Arjomand|2007|pp=134–136}} | |||
Around the time when Ibn al-Zubayr was trying to expand his dominion, the pro-Alid revolutionary ] took control of the Iraqi garrison town of ] in the name of Ali's son ], whom he proclaimed as the Mahdi in the messianic sense.{{sfn|Madelung|1986|p=1231}} The association of the name Muhammad with the Mahdi seems to have originated with Ibn al-Hanafiyya, who also shared the epithet Abu al-Qasim with Muhammad, the Islamic prophet.{{sfn|Madelung|1986|p=1232}} Among the Umayyads, the caliph ] ({{Reign|715|717}}) encouraged the belief that he was the Mahdi, and other Umayyad rulers, like ] ({{Reign|717|720}}), have been addressed as such in the ] of ] ({{Died in|728}}) and ] ({{Died in|728–730}}).{{sfn|Madelung|1986|p=1231}} | |||

Early discussions about the identity of the Mahdi by religious scholars can be traced back to the time after the ]. These discussions developed in different directions and were influenced by traditions (]) attributed to Muhammad. In Umayyad times, scholars and traditionists not only differed on which caliph or rebel leader should be designated as Mahdi but also on whether the Mahdi is a messianic figure and if signs and predictions of his time had been satisfied. In Medina, among the conservative religious circles, the belief in Umar ibn Abd al-Aziz being the Mahdi was widespread. ] ({{Died in|715}}) is said to identify Umar ibn Abd al-Aziz as the Mahdi long before his reign. The Basran, Abu Qilabah, supported the view that Umar ibn Abd al-Aziz was the Mahdi. ] ({{Died in|728}}) opposed the concept of a Muslim Messiah but believed that if there was the Mahdi, it was Umar ibn Abd al-Aziz.{{sfn|Madelung|1986|pp=1231–1232}} | |||
The zebra finch (or at the very least, the subspecies ''T. g. castanotis'') is generally found in more arid areas.<ref name="hbwc"/> The areas it chooses to occupy are close to water, and places where rain is concentrated after it falls.<ref name="Zann23">{{harvnb|Zann|1996|p=23}}</ref> However, this is likely more related to the abundance of vegetation than the abundance of water as a resource in itself.<ref name="Zann62–68">{{harvnb|Zann|1996|p=62–68}}</ref>.

By the time of the ] in 750, Mahdi was already a known concept.<ref name="Britannica">{{cite web |title=Mahdī Islamic concept |url=https://www.britannica.com/topic/mahdi |access-date=22 May 2022 |website=Britannica}}</ref> Evidence shows that the first Abbasid caliph ] ({{Reign|750|754}}) assumed the title of "the Mahdi" for himself.{{sfn|Madelung|1986|p=1233}} | |||
Although zebra finch breeding, for example, is initiated by rainfall,<ref name="ZannMorton1995"/> ] proposed that sustained heavy precipitation is detrimental to the zebra finch. This is supported by the observation that the nest does not shield the chicks or eggs from rain, and rainfall can sometimes result in clutches being abandoned. Furthermore, it is supported by Immelmann's finding that zebra finches left ] after the first heavy rains in November 1959, but returned to breed in April. It is hypothesized that birds in parts of northern Australia migrate inland during the wet season from October to May, and return to the coastal regions during the dryer months.<ref name="Zann25">{{harvnb|Zann|1996|p=25}}</ref> | |||

=== Shia Islam === | ||
In Shia Islam, the eschatological Mahdi was commonly given the epithet al-Qa'im ({{Lang|ar|القائم}}),{{Sfn|Madelung|1986}}{{Sfn|Hussain|1986|pp=144–145}} which can be translated as 'he who will rise,'{{Sfn|Amir-Moezzi|1998}} signifying his rise against tyranny in the end of time.{{Sfn|Sachedina|1981|p=60}} Distinctively Shia is the notion of temporary absence or ] of the Mahdi,{{Sfn|Madelung|1986}} whose life has been prolonged by divine will.{{Sfn|Sobhani|2001|p=118}}{{Sfn|Momen|1985|p=165}} An intimately related Shia notion is that of {{Transliteration|ar|raj'a}} ({{lit|return}}),{{Sfn|Amir-Moezzi|1998}}{{Sfn|Momen|1985|p=166}} which often means the return to life of (some) Shia Imams, particularly ], to exact their revenge on their oppressors.{{Sfn|Amir-Moezzi|1998}}{{Sfn|Kohlberg|2022}} | |||
The life expectancy of a zebra finch is highly variable because of genetic and environmental factors. The zebra finch may reach up to five years in its natural environment. If they are kept caged, they normally live for 5 to 9 years but may live as long as 12 years,<ref name= awd>{{cite web|url=http://animaldiversity.ummz.umich.edu/site/accounts/information/Taeniopygia_guttata.html | title=Taeniopygia guttata|accessdate=22 July 2009|work=Animal Diversity Web|publisher=University of Michigan|year=2007|author1=White, R. |author2=Fraser, A. |lastauthoramp=yes }}</ref> with an exceptional case of 14.5 years reported for a caged specimen.<ref>{{cite web|url=http://genomics.senescence.info/species/entry.php?species=Taeniopygia_guttata |title=AnAge entry for Taeniopygia guttata |publisher=Genomics.senescence.info |accessdate=25 January 2011}}</ref> The greatest threats to zebra finch survival are predation by cats and loss of natural food.<ref name="goldenb">{{cite book |title=The Golden Book of Australian birds and mammals |last=Haddon |first=Frank |others=Illustrated by Tony Oliver|year=1985 |publisher=Golden Press |isbn=0-7302-0011-6 |page=44 }}</ref> | |||
Traditions that predicted the occultation and rise of a future imam were already in circulation for a century before the death of the eleventh Imam in 260 (874 CE),{{Sfn|Modarressi|1993|pp=87, 88}}{{Sfn|Amir-Moezzi|1998}} and possibly as early as the seventh-century CE.{{Sfn|Amir-Moezzi|1998}} These traditions were appropriated by various Shia sects in different periods,{{sfn|Kohlberg|2009|p=531}} including the now-extinct sects of Nawusites and ]. {{Sfn|Hussain|1989|pp=12–13}} For instance, these traditions were cited by the now-extinct ], who denied the death of Ibn al-Hanafiyya,{{Sfn|Madelung|1986}}{{Sfn|Sachedina|1981|p=151}} and held that he was in hiding in the Razwa mountains near ].{{sfn|Arjomand|2007|pp=134–136}} This likely originated with two groups of his supporters, namely, southern Arabian settlers and local recent converts in ], who seem to have spread the notions now known as occultation and {{Transliteration|ar|raj'a}}.{{sfn|Arjomand|2007|pp=134–136}} Later on, these traditions were also employed by the ] to argue that ], the seventh Imam, had not died but was in occultation.{{Sfn|Modarressi|1993|pp=87, 88}} | |||
==Song and other vocalizations== | |||
Zebra finches are loud and boisterous singers. Their calls can be a loud ''beep'', ''meep'', ''oi!'' or ''a-ha!''. Their song is a few small beeps, leading up to a rhythmic song of varying complexity in males. Each male's song is different, although birds of the same bloodline will exhibit similarities, and all finches will overlay their own uniqueness onto a common rhythmic framework. Sons generally learn the song of their fathers with little variation. There is a critical sensitive period during which juvenile males learn their songs by imitating a mature, male tutor.<ref name=":0">{{Cite journal|last=Brainard|first=Michael S.|last2=Doupe|first2=Allison J.|date=16 May 2002|title=What songbirds teach us about learning|url=http://www.nature.com/nature/journal/v417/n6886/full/417351a.html|journal=Nature|language=en|volume=417|issue=6886|pages=351–358|doi=10.1038/417351a|issn=0028-0836|pmid=12015616}}</ref> Subsong (early, poorly structured vocalizations) evolve into 'plastic song'. This plastic song is variable between renditions but begins to incorporate some recognizable elements of tutor songs.<ref name=":0" /> A study conducted by Nottebohm et al., has shown that birds were able to successfully imitate their tutor’s song after relatively short exposure (40 playbacks of the motifs lasting 30 seconds total) over the duration of their sensitive learning period.<ref>{{Cite journal|last=Tchernichovski|first=Ofer|last2=Lints|first2=Thierry|last3=Mitra|first3=Partha P.|last4=Nottebohm|first4=Fernando|date=26 October 1999|title=Vocal imitation in zebra finches is inversely related to model abundance|journal=Proceedings of the National Academy of Sciences of the United States of America|volume=96|issue=22|pages=12901–12904|issn=0027-8424| pmc=23154 |pmid=10536020|doi=10.1073/pnas.96.22.12901}}</ref> These birds eventually form a “template” of what their correct song should sound like. They rely on auditory feedback for both song learning and practice as juveniles and song maintenance as adults. Adult birds maintain their songs by correcting any deviations from their target song template. During adulthood, by around 90 days, the bird's song goes through a crystallization phase where their song template is stable and it no longer changes.<ref name=":0" /> | |||
In parallel, traditions predicting the occultation of a future imam also persisted in the writings of the mainstream Shia, who later formed the Twelvers.{{Sfn|Kohlberg|2009|p=531}}{{Sfn|Madelung|1986}} Based on this material, the Twelver doctrine of occultation crystallized in the first half of the fourth (tenth) century,{{Sfn|Daftary|2013|p=67}} in the works of ] ({{Died in|919}}), ] ({{Died in|941}}), and ] ({{Died in|991}}), among others.{{Sfn|Kohlberg|2009}} This period also saw a transition in Twelver arguments from a traditionist to a rationalist approach in order to vindicate the occultation of the twelfth Imam. {{Sfn|Sachedina|1981|pp=79, 80}}{{Sfn|Arjomand|2000}} | |||
Male zebra finches begin to sing at puberty, while females lack a singing ability.<ref name= awd/> This is due to a developmental difference, where in the embryo, the male zebra finch produces testosterone, which is transformed into estradiol in the brain, which in turn leads to the development of the nervous system for a song system.<ref>{{cite journal|last1=Gahr|first1=M|last2=Konishi|first2=M.|year=1988|title=Developmental changes in estrogen-sensitive neurons in the forebrain of the zebra finch|journal=Proceedings of the National Academy of Sciences|volume=85|issue=19|pages=7380–7383|doi=10.1073/pnas.85.19.7380 |url=http://authors.library.caltech.edu/1609/1/GAHpnas88.pdf}}</ref> There are multiple areas of the brain involved in the production of song.

The zebra finch uses an acoustic signal to communicate to embryos. It gives an incubation call to its eggs when the weather is hot—above {{convert|26|C|F}}—and when the end of their incubation period is near. This call alters the growth and behaviour of the chicks, with chicks that were given an incubation call having less mass at the end of the nestling phase when they experienced higher nest temperatures. This contrasts with chicks that were not given an incubation call, which have a higher mass at the end of nestling after being exposed to high nest temperatures. Additionally, the chicks called to as an embryo are more likely to call after experiencing high nest temperatures.<ref>{{cite journal|last1=Mariette|first1=Mylene M.|last2=Buchanan|first2=Katherine L.|year=2016|title=Prenatal acoustic communication programs offspring for high posthatching temperatures in a songbird.|journal=Science|volume=353|issue=6301|pages=812–814|doi=10.1126/science.aaf7049}}</ref> | |||

The zebra finch generally breeds in loose colonies of up to 50 nests (although the number of individuals in a colony can be up to about 230 when breeding, and around 350 when not), but it may nest solitarily.<ref name="Zann27"/> It often does not breed in the colony it was born; of the ringed birds that bred in the Danaher breeding colony ({{Coord|36|09|S|145|26|E}}) from 1985 to 1989, 24% of them were hatched from the colony or in the immediate vicinity. Additionally, ] is not sex-biased, unlike in most passerines. However, males between 36 and 50 days of age are more likely to disperse than females, although after this age, more females disperse than males.<ref name="ZannRunciman2008"/> Predation is likely a major factor in coloniality; nests in the main colony suffer less predation than nests further away.

In addition, reproductive success of conspecifics may play a role in where individuals nest; a study published in 2012 found that this finch was more likely to breed near nests with chicks older than six days (used as a proxy for reproductive success because they fledge about 87% of the time).<ref name="MarietteGriffith2012">{{cite journal|last1=Mariette|first1=Mylene M.|last2=Griffith|first2=Simon C.|title=Conspecific attraction and nest site selection in a nomadic species, the zebra finch|journal=Oikos|volume=121|issue=6|year=2012|pages=823–834|issn=00301299|doi=10.1111/j.1600-0706.2011.20014.x}}</ref> The zebra finch usually places its nest in a thorny shrub or tree, although it will nest in other structures, natural and artificial.<ref name="Zann27"/> Often, there are multiple nests in one shrub.<ref name="hbwc"/> | |||

This is so that the young hatch when semi-ripe and ripe seeds (their primary food) become available.

The zebra finch generally forages for seeds on the ground, taking them individually. But, it also eats seeds on the heads of standing grass. To do this, it either flies and pecks out seeds one at a time, or it perches on a nearby branch. It may also take the head to the ground by jumping up and seizing it with its bill or feet. In times of scarcity, the zebra finch can use its bill to dig into the ground to find buried seed.<ref name="Zann51–52">{{harvnb|Zann|1996|pp=51–52}}</ref> These seeds are generally taken from patches which have fewer husks (when compared to the number of whole seeds) and are larger and more dense.

Birds that arrive in this flock later are more likely to rely on scrounging, or taking food from competitors, whereas early arrivals are more likely to find food for themselves.

Foraging activity in the zebra finch peaks in the first hour after sunrise and the second to last hour before sunset. In the first instance, the increase foraging is generally achieved through many short bouts of foraging, whereas the latter comes from a few long bouts.<ref name="Slater1974"/> When food becomes less available, like from August to September in northern Victoria, there is more feeding in the afternoon, less time spent on patches of food before leaving, and the distance between places where food is available is longer.<ref name="Zann46"/> There are generally two groups of individuals based on foraging behaviour. In the first group, the probability of starting or stopping a feeding bout is constant through time, and short meals are more usual. Most birds in this group have longer bouts when the gap between the previous bout is longer. In the second group (which may consist of more birds), the longer a gap is, the more likely the individual is to start feeding again. Additionally, for most birds in this group, the same is true of the stopping of a bout; the longer it is, the more likely it is to be stopped.

===Drinking and bathing=== | |||
The zebra finch generally consumes about 24% to 28% of its body weight (or about {{convert|3|mL|floz}}) in water per day at a temperature of {{convert|22|to|23|C|F}}. When at a higher temperature of {{convert|40|C|F}}, it may drink from {{convert|6|to|12|mL|floz}} of water per day. The zebra finch also extracts water from seeds, and can get water from metabolizing its food. This metabolic water consumption can equal the amount of water that is lost when temperatures are below {{convert|23|C|F}}, although only for birds that are gradually dehydrated. Suddenly dehydrated birds must be in temperatures below {{convert|12|C|F}} before the water lost is equal to that produced by the metabolism. This finch can survive periods of low water consumption; one study that gradually reduced the amount of water given over a period of a few months to just {{convert|0.5|to|1|ml|floz}} per week at temperatures from {{convert|22|to|24|C|F}} found that the zebra finch could survive these conditions.

It prefers to drink from small puddles or other collections of water, especially those with gently sloped banks. Additionally, exposed drinking areas are preferred to more enclosed ones. It can also drink from dew on the tip of leaves. Due to the danger of predation, the zebra finch gathers in flocks in a bush or tree near a waterhole, only going to drink after the group is large enough. It then only drinks for a few seconds. After drinking, the zebra finch generally bathes for around a minute. Then, it dries off and re-oils its plumage in a warm sheltered spot.<ref name="Zann62–68"/> | |||

The zebra finch only needs an average of 3.6 seconds to drink {{convert|1.5|mL|floz}} of water. This short amount of time per bout is achieved by this finch's drinking method. It swallows the water it gets while its bill tip is still submerged, unlike most birds that bring their bill tip up to swallow. This unique action is accomplished by having the tongue scoop water into the pharynx. Then, the front of the larynx forces the water into the oesophagus, which, through peristalsis, takes the fluid to the crop. This method could have evolved because the adaptations necessary were already there because of the need to quickly dehusk and swallow seeds. It allows for water to be drunk faster and taken from more diverse sources, such as drops of dew<ref name="Zann60–62">{{harvnb|Zann|1996|pp=60–62}}</ref><ref name="HeidweillerZweers1990"/> and cattle troughs; the latter requires the bird to drink upside down.<ref name="HeidweillerZweers1990">{{cite journal|last1=Heidweiller|first1=J.|last2=Zweers|first2=G.

Ibn Khaldun noted a pattern where embracing a Mahdi claimant enabled unity among tribes and/or a region, often enabled them to forcibly seize power, but the lifespan of such a force was usually limited,<ref name=JPFAiI2011:64-5>]: pp. 64–65</ref> as their Mahdi had to conform to hadith prophesies—winning their battles and bringing peace and justice to the world before Judgement Day—which (so far) none have. | |||

The Mahdi (Arabic: ٱلْمَهْدِيّ, romanized: al-Mahdī, lit. 'the Guided'; Persian: مهدی) is a figure in Islamic eschatology who is believed to appear at the End of Times to rid the world of evil and injustice. He is said to be a descendant of Muhammad, who will appear shortly before Jesus.
The Mahdi is mentioned in several canonical compilations of hadith, but is absent from the Quran and the two most-revered Sunni hadith collections, Sahih al-Bukhari and Sahih Muslim. Thus, some Sunni theologians have questioned the orthodoxy of the Mahdi. The doctrine of the Mahdi seems to have gained traction during the confusion and unrest of the religious and political upheavals of the first and second centuries of Islam. Some of the first references to the Mahdi appear in the late 7th century, when the revolutionary Mukhtar al-Thaqafi declared Muhammad ibn al-Hanafiyya, a son of Caliph Ali (r. 656–661), to be the Mahdi. Although the concept of a Mahdi is not an essential doctrine in Islam, it is popular among Muslims. Over centuries, there have been a vast number of Mahdi claimants.
The Mahdi features in both Shia and Sunni branches of Islam, though they differ extensively on his attributes and status. Among Twelver Shias, the Mahdi is believed to be Imam Muhammad al-Mahdi, twelfth Imam, son of the eleventh Imam, Hasan al-Askari (d. 874), who is said to be in occultation (ghayba) by divine will. This is rejected by Sunnis, who assert that the Mahdi has not been born yet.
Etymology
The term Mahdi is derived from the Arabic root h-d-y (ه-د-ي), commonly used to mean "divine guidance". Although the root appears in the Qur'an at multiple places and in various contexts, the word Mahdi never occurs in the book. The associated verb is hada, which means to guide. However, Mahdi can be read in active voice, where it means the one who guides, as well as passive voice, where it means the one who is guided.
Historical development
Pre-Islamic ideas
Some historians suggest that the term itself was probably introduced into Islam by southern Arabian tribes who had settled in Syria in the mid-7th century. They believed that the Mahdi would lead them back to their homeland and re-establish the Himyarite Kingdom. They also believed that he would eventually conquer Constantinople. It has also been suggested that the concept of the Mahdi may have been derived from earlier messianic Jewish and Christian beliefs. Accordingly, traditions were introduced to support certain political interests, especially anti-Abbasid sentiments. These traditions about the Mahdi appeared only at later times in hadith books such as Sunan Abi Dawud and Sunan al-Tirmidhi, but are absent from the early works of Muhammad al-Bukhari and Muslim ibn al-Hajjaj.
Origin
The term al-Mahdi was employed from the beginning of Islam, but only as an honorific epithet ("the guide") and without any messianic significance. As an honorific, it was used in some instances to describe Muhammad (by Hassan ibn Thabit), Abraham, al-Husayn, and various Umayyad caliphs (هداة مهديون, hudat mahdiyyun). During the Second Muslim Civil War (680–692), after the death of Mu'awiya I (r. 661–680), the term acquired a new meaning of a ruler who would restore Islam to its perfect form and restore justice after oppression. Abd Allah ibn al-Zubayr, who laid claim to the caliphate against the Umayyads and found temporary success during the civil war, presented himself in this role. Although the title Mahdi was not applied to him, his career as the anti-caliph significantly influenced the future development of the concept. A hadith was promulgated in which Muhammad prophesies the coming of a just ruler.
There will arise a difference after the death of a caliph, and a man of the people of Medina will go forth fleeing to Mecca. Then some of the people of Mecca will come to him and will make him rise in revolt against his will ... An expedition will be sent against him from Syria but will be swallowed up ... in the desert between Mecca and Medina. When the people see this, the righteous men ... of Syria and ... Iraq will come to him and pledge allegiance to him. Thereafter a man of the Quraysh will arise whose maternal uncles are of Kalb. He will send an expedition against them, but they will defeat them ... He will then divide the wealth and act among them according to the Sunna of their Prophet. Islam will settle down firmly on the ground ... He will stay seven years and then die, and the Muslims will pray over him.
Refusing to recognize the new caliph, Yazid I (r. 680–683), after Mu'awiya's death in 680, Ibn al-Zubayr had fled to the Meccan sanctuary. From there he launched anti-Umayyad propaganda, calling for a shura of the Quraysh to elect a new caliph. Those opposed to the Umayyads were paying him homage and asking for the public proclamation of his caliphate, forcing Yazid to send an army to dislodge him in 683. After defeating rebels in the nearby Medina, the army besieged Mecca but was forced to withdraw as a result of Yazid's sudden death shortly afterward. Ibn al-Zubayr was recognized caliph in Arabia, Iraq, and parts of Syria, where Yazid's son and successor Mu'awiya II (r. 683–684) held power in Damascus and adjoining areas. The hadith hoped to enlist support against an expected Umayyad campaign from Syria. The Umayyads did indeed send another army to Mecca in 692, but contrary to the hadith's prediction was successful in removing Ibn al-Zubayr. The hadith lost relevance soon afterward, but resurfaced in the Basran hadith circles a generation later, this time removed from its original context and understood as referring to a future restorer.
Around the time when Ibn al-Zubayr was trying to expand his dominion, the pro-Alid revolutionary al-Mukhtar al-Thaqafi took control of the Iraqi garrison town of Kufa in the name of Ali's son Muhammad ibn al-Hanafiyya, whom he proclaimed as the Mahdi in the messianic sense. The association of the name Muhammad with the Mahdi seems to have originated with Ibn al-Hanafiyya, who also shared the epithet Abu al-Qasim with Muhammad, the Islamic prophet. Among the Umayyads, the caliph Sulayman ibn Abd al-Malik (r. 715–717) encouraged the belief that he was the Mahdi, and other Umayyad rulers, like Umar ibn Abd al-Aziz (r. 717–720), have been addressed as such in the panegyrics of Jarir (d. 728) and al-Farazdaq (d. 728–730).
Early discussions about the identity of the Mahdi by religious scholars can be traced back to the time after the Second Fitna. These discussions developed in different directions and were influenced by traditions (hadith) attributed to Muhammad. In Umayyad times, scholars and traditionists not only differed on which caliph or rebel leader should be designated as Mahdi but also on whether the Mahdi is a messianic figure and if signs and predictions of his time had been satisfied. In Medina, among the conservative religious circles, the belief in Umar ibn Abd al-Aziz being the Mahdi was widespread. Said ibn al-Musayyib (d. 715) is said to identify Umar ibn Abd al-Aziz as the Mahdi long before his reign. The Basran, Abu Qilabah, supported the view that Umar ibn Abd al-Aziz was the Mahdi. Hasan al-Basri (d. 728) opposed the concept of a Muslim Messiah but believed that if there was the Mahdi, it was Umar ibn Abd al-Aziz.
By the time of the Abbasid Revolution in 750, Mahdi was already a known concept. Evidence shows that the first Abbasid caliph al-Saffah (r. 750–754) assumed the title of "the Mahdi" for himself.
Shia Islam
In Shia Islam, the eschatological Mahdi was commonly given the epithet al-Qa'im (القائم), which can be translated as 'he who will rise,' signifying his rise against tyranny in the end of time. Distinctively Shia is the notion of temporary absence or occultation of the Mahdi, whose life has been prolonged by divine will. An intimately related Shia notion is that of raj'a (lit. 'return'), which often means the return to life of (some) Shia Imams, particularly Husayn ibn Ali, to exact their revenge on their oppressors.
Traditions that predicted the occultation and rise of a future imam were already in circulation for a century before the death of the eleventh Imam in 260 (874 CE), and possibly as early as the seventh-century CE. These traditions were appropriated by various Shia sects in different periods, including the now-extinct sects of Nawusites and Waqifites. For instance, these traditions were cited by the now-extinct Kaysanites, who denied the death of Ibn al-Hanafiyya, and held that he was in hiding in the Razwa mountains near Medina. This likely originated with two groups of his supporters, namely, southern Arabian settlers and local recent converts in Iraq, who seem to have spread the notions now known as occultation and raj'a. Later on, these traditions were also employed by the Waqifites to argue that Musa al-Kazim, the seventh Imam, had not died but was in occultation.
In parallel, traditions predicting the occultation of a future imam also persisted in the writings of the mainstream Shia, who later formed the Twelvers. Based on this material, the Twelver doctrine of occultation crystallized in the first half of the fourth (tenth) century, in the works of Ibrahim al-Qummi (d. 919), Ya'qub al-Kulayni (d. 941), and Ibn Babawayh (d. 991), among others. This period also saw a transition in Twelver arguments from a traditionist to a rationalist approach in order to vindicate the occultation of the twelfth Imam.
The Twelver authors also aim to establish that the description of Mahdi in Sunni sources applies to the twelfth Imam. Their efforts gained momentum in the seventh (thirteenth) century when some notable Sunni scholars endorsed the Shia view of the Mahdi, including the Shafi'i traditionist Muhammad ibn Yusuf al-Gandji. Since then, Amir-Moezzi writes, there is Sunni support from time to time for the Twelvers' view of Mahdi. There has also been some support for the mahdiship of the twelfth Imam in Sufi circles, for instance, by the Egyptian Sufi al-Sha'rani.
Before the rise of the Fatimid Caliphate, as a major Isma'ili Sh'a dynasty, the terms Mahdi and Qa'im were used interchangeably for the messianic imam anticipated in Shia traditions. With the rise of the Fatimids in the tenth century CE, however, al-Qadi al-Nu'man argued that some of these predictions had materialized by the first Fatimid caliph, Abd Allah al-Mahdi Billah, while the rest would be fulfilled by his successors. Henceforth, their literature referred to the awaited eschatological imam only as Qa'im (instead of Mahdi). In Zaydi view, imams are not endowed with superhuman qualities, and expectations for their mahdiship are thus often marginal. One exception is the now-extinct Husaynites in Yemen, who denied the death of al-Husayn ibn al-Qasim al-Iyani and awaited his return.
In Islamic doctrine
Sunni Islam
In Sunni Islam, the Mahdi doctrine is not theologically important and remains as a popular belief instead. Of the six canonical Sunni hadith compilations, three—Abi Dawud, Ibn Maja, and al-Tirmidhi—contain traditions on the Mahdi; the compilations of al-Bukhari and Muslim—considered the most authoritative by the Sunnis and the earliest of the six—do not, nor does al-Nasa'i. Some Sunnis, including the philosopher and historian Ibn Khaldun (d. 1406), and reportedly also Hasan al-Basri, an influential early theologian and exegete, deny the Mahdi being a separate figure, holding that Jesus will fulfill this role and judge over mankind; Mahdi is thus considered a title for Jesus when he returns. Others, like the historian and the Qur'an commentator Ibn Kathir (d. 1373), elaborated a whole apocalyptic scenario which includes prophecies about the Mahdi, Jesus, and the Dajjal (the antichrist) during the end times.
The common opinion among the Sunnis is that the Mahdi is an expected ruler to be sent by God before the end times to re-establish righteousness. He is held to be from among the descendants of Muhammad through his daughter Fatima and her husband Ali, and his physical characteristics including a broad forehead and curved nose. He will eradicate injustice and evil from the world. He will be from the Hasanid branch of Muhammad's descendants, as opposed to the Shia belief that he is of the Husaynid line. The Mahdi's name would be Muhammad and his father's name would be Abd Allah. Abu Dawud quotes Muhammad as saying: "The Mahdi will be from my family, from the descendants of Fatimah". Another hadith states:
Even if only one day remains , God will lengthen this day until He calls forth a man from me, or from the family of my house, his name matching mine and his father's name matching that of my father. He will fill the Earth with equity and justice just as it had previously been filled with injustice and oppression.
Before the arrival of the Mahdi, the earth would be filled with anarchy and chaos. Divisions and civil wars, moral degradation, and worldliness would be prevalent among the Muslims. Injustice and oppression would be rampant in the world. In the aftermath of the death of a king, the people would quarrel among themselves, and the as yet unrecognized Mahdi would flee from Medina to Mecca to take refuge in the Ka'ba. He would be the Mahdi recognized as ruler by the people. The Dajjal would appear and will spread corruption in the world. With an army bearing black banners, which would come to his aid from the east, the Mahdi would fight the Dajjal, and will be able to defeat him. Dressed in saffron robes with his head anointed, Jesus would descend at the point of a white minaret of the Umayyad Mosque in eastern Damascus (believed to be the Minaret of Jesus) and join the Mahdi. Jesus would pray behind the Mahdi and then kill the Dajjal. The Gog and Magog would also appear wreaking havoc before their final defeat by the forces of Jesus. Although not as significant as the Dajjal and the Gog and Magog, the Sufyani, another representative of the forces of dark, also features in the Sunni traditions. He will rise in Syria before the appearance of Mahdi. When the latter appears, the Sufyani, along with his army, will either be swallowed up en route to Mecca by the earth with God's command or defeated by the Mahdi. Jesus and the Mahdi will then conquer the world and establish caliphate. The Mahdi will die after 7 to 13 years, whereas Jesus after 40 years. Their deaths would be followed by reappearance of corruption before the final end of the world.
Shia Islam
Twelver
Main article: Muhammad al-Mahdi Further information: Occultation (Islam) and Qa'im Al MuhammadIn Twelver Shi'ism, the largest Shia branch, the belief in the messianic imam is not merely a part of creed, but the pivot. For the Twelver Shia, the Mahdi was born but disappeared, and would remain hidden from humanity until he reappears to bring justice to the world in the end of time, a doctrine known as the Occultation. This imam in occultation is the twelfth imam, Muhammad, son of the eleventh imam, Hasan al-Askari. According to the Twelvers, the Mahdi was born in Samarra around 868, though his birth was kept hidden from the public. He lived under his father's care until 874 when the latter was killed by the Abbasids.
Minor Occultation
When his father died in 874, possibly poisoned by the Abbasids, the Mahdi went into occultation by the divine command and was hidden from public view for his life was in danger from the Abbasids. Only a few of the elite among the Shia, known as the deputies (سفراء, sufara; sing. سفير safir) of the twelfth imam, were able to communicate with him; hence the occultation in this period is referred to as the Minor Occultation (ghayba al-sughra).
The first of the deputies is held to have been Uthman ibn Sa'id al-Amri, a trusted companion and confidant of the eleventh imam. Through him the Mahdi would answer the demands and questions of the Shia. He was later succeeded by his son Muhammad ibn Uthman al-Amri, who held the office for some fifty years and died in 917. His successor Husayn ibn Rawh al-Nawbakhti was in the office until his death in 938. The next deputy, Ali ibn Muhammad al-Simari, abolished the office on the orders of the imam just a few days before his death in 941.
Major Occultation
With the death of the fourth agent, thus began the Major Occultation (الغيبة الكبرى, ghayba al-kubra), in which the communication between the Mahdi and the faithful was severed. The leadership vacuum in the Twelver community was gradually filled by jurists. During the Major Occultation, the Mahdi roams the earth and is sustained by God. He is the lord of the time (صاحب الزمان sahib az-zamān) and does not age. Although his whereabouts and the exact date of his return are unknown, the Mahdi is nevertheless believed to contact some of his Shia if he wishes. The accounts of these encounters are numerous and widespread in the Twelver community. Shia scholars have argued that the longevity of the Mahdi is not unreasonable given the long lives of Khidr, Jesus, and the Dajjal, as well as secular reports about long-lived men. Along these lines, Tabatabai emphasizes the miraculous qualities of al-Mahdi, adding that his long life, while unlikely, is not impossible. He is viewed as the sole legitimate ruler of the Muslim world and the constitution of the Islamic Republic of Iran recognizes him as the head of the state.
Reappearance
Before his reappearance (Arabic: ظهور, romanized: ṭuhūr), the world will plunge into chaos, where immorality and ignorance will be commonplace, the Qur'an will be forgotten, and religion will be abandoned. There will be plagues, earthquakes, floods, wars and death. The Sufyani will rise and lead people astray. The Mahdi will then reappear in Mecca, with the sword of Ali (ḏū l-fiqār) in his hand, between the corner of the Ka'ba and the station of Abraham.
By some accounts, he will reappear on the day of Ashura (the tenth of Muharram), the day the third Imam Husayn ibn Ali was slain. He will be "a young man of medium stature with a handsome face," with black hair and beard. A divine cry will call the people of the world to his aid, after which the angels, jinns, and humans will flock to the Mahdi. This is often followed shortly by another supernatural cry from the earth that invites men to join the enemies of the Mahdi, and would appeal to disbelievers and hypocrites.
The Mahdi will then go to Kufa, which will become his capital, and send troops to kill the Sufyani in Damascus. Husayn and his slain partisans are expected to resurrect to avenge their deaths, known as the doctrine of raj'a (lit. 'return'). The episode of Jesus' return in the Twelver doctrine is similar to the Sunni belief, although in some Twelver traditions it is the Mahdi who would kill the Dajjal. Those who hold enmity towards Ali (Arabic: نَواصِب, romanized: nawāṣib, lit. 'haters') will be subject to jizya (poll tax) or killed if they do not accept Shia Islam.
The Mahdi is also viewed as the restorer of true Islam, and the restorer of other monotheistic religions after their distortion and abandonment. He establishes the kingdom of God on earth and Islamizes the whole world. In their true form, it is believed, all monotheistic religions are essentially identical to Islam as "submission to God." It is in this sense, according to Mohammad Ali Amir Moezzi, that one should understand the claims that al-Mahdi will impose Islam on everyone. His rule will be paradise on earth, which will last for seventy years until his death, though other traditions state 7, 19, or 309 years.
Isma'ilism
In Isma'ilism a distinct concept of the Mahdi developed, with select Isma'ili Imams representing the Mahdi or al-Qa'im at various times. When the sixth Shia imam Ja'far al-Sadiq died, some of his followers held his already dead son Isma'il ibn Ja'far to be the imam asserting that he was alive and will return as the Mahdi. Another group accepted his death and acknowledged his son Muhammad ibn Isma'il as the imam instead. When he died, his followers too denied his death and believed that he was the last imam and the Mahdi. By the mid-9th century, Isma'ili groups of different persuasions had coalesced into a unified movement centered in Salamiyya in central Syria, and a network of activists was working to collect funds and amass weapons for the return of the Mahdi Muhammad ibn Isma'il, who would overthrow the Abbasids and establish his righteous caliphate. The propaganda of the Mahdi's return had a special appeal to peasants, Bedouins, and many of the later-to-be Twelver Shias, who were in a state of confusion (hayra) in the aftermath of the death of their 11th imam Hasan al-Askari, and resulted in many conversions.
In 899, the leader of the movement, Sa'id ibn al-Husayn, declared himself the Mahdi. This brought about schism in the unified Isma'ili community as not all adherents of the movement accepted his Mahdist claims. Those in Iraq and Arabia, known as Qarmatians after their leader Hamdan Qarmat, still held that Muhammad ibn Isma'il was the awaited Mahdi and denounced the Salamiyya-based Mahdism. In the Qarmati doctrine, the Mahdi was to abrogate the Islamic law (the Sharia) and bring forth a new message. In 931, the then Qarmati leader Abu Tahir al-Jannabi declared a Persian prisoner named Abu'l-Fadl al-Isfahani as the awaited Mahdi. The Mahdi went on to denounce Moses, Jesus, and Muhammad as liars, abolished Islam, and instituted the cult of fire. Abu Tahir had to depose him as imposter and had him executed.
Meanwhile, in Syria, Sa'id ibn al-Husayn's partisans took control of the central Syria in 903, and for a time the Friday sermon was read in the name of the "Successor, the rightly-guided Heir, the Lord of the Age, the Commander of the Faithful, the Mahdi". Eventually, the uprising was routed by the Abbasids. This forced Sa'id to flee from Syria to North Africa, where he founded the Fatimid Caliphate in Ifriqiya in 909. There he assumed the regnal name al-Mahdi Billah; as the historian Heinz Halm comments, the singular, semi-divine figure of the Mahdi was thus reduced to an adjective in a caliphal title, 'the Imam rightly guided by God' (al-imam al-mahdi bi'llah): instead of the promised messiah, al-Mahdi presented himself merely as one in a long sequence of imams descending from Ali and Fatima.
Messianic expectations associated with the Mahdi nevertheless did not materialize, contrary to the expectations of his propagandists and followers who expected him to do wonders. Al-Mahdi attempted to downplay messianism and asserted that the propaganda of Muhammad ibn Isma'il's return as the Mahdi had only been a ruse to avoid Abbasid persecution and protect the real imam predecessors of his. The Mahdi was actually a collective title of the true imams from the progeny of Ja'far al-Sadiq. In a bid to gain time, al-Mahdi also sought to shift the messianic expectations on his son, al-Qa'im: by renaming himself as Abdallah Abu Muhammad, and his son as Abu'l-Qasim Muhammad rather than his original name, Abd al-Rahman, the latter would bear the name Abu'l-Qasim Muhammad ibn Abdallah. This was the name of the Islamic prophet Muhammad, and it had been prophesied that the Mahdi would also bear it. The Fatimids eventually dropped the millenarian rhetoric.
The Tayyibi Musta'li Isma'ili Shia believe that their Occulted Imam and Mahdi is Abu'l-Qasim al-Tayyib, son of the Fatimid Caliph Al-Amir bi-Ahkam Allah.
Zaydism
In Zaydism, the concept of imamate is different from the Isma'ili and Twelver branches; a Zaydi Imam is any respectable person from the descendants of Ali and Fatima who lays claim to political leadership and struggles for its acquisition. As such, the Zaydi imamate doctrine lacks eschatological characteristics and there is no end-times redeemer in Zaydism. The title of mahdi has been applied to several Zaydi imams as an honorific over the centuries.
Ahmadiyya belief
Further information: Mirza Ghulam AhmadIn the Ahmadiyya belief, the prophesied eschatological figures of Christianity and Islam, the Messiah and Mahdi, actually refer to the same person. These prophecies were fulfilled in Mirza Ghulam Ahmad (1835–1908), the founder of the movement; he is held to be the Mahdi and the manifestation of Jesus. However, the historical Jesus in their view, although escaped crucifixion, nevertheless died and will not be coming back. Instead, God made Mirza Ghulam Ahmad the exact alike of Jesus in character and qualities. Similarly, the Mahdi is not an apocalyptic figure to launch global jihad and conquer the world, but a peaceful mujaddid (renewer of religion), who spreads Islam with "heavenly signs and arguments".
Mahdi claimants
Main article: List of Mahdi claimantsThroughout history, various individuals have claimed to be or were proclaimed to be the Mahdi. Claimants have included Muhammad Jaunpuri, the founder of the Mahdavia sect; Ali Muhammad Shirazi, the founder of Bábism; Muhammad Ahmad, who established the Mahdist State in Sudan in the late 19th century. The Iranian dissident Massoud Rajavi, the leader of the MEK, also claimed to be a 'representative' of the Mahdi. The adherents of the Nation of Islam hold Wallace Fard Muhammad, the founder of the movement, to be the Messiah and the Mahdi. Adnan Oktar, a Turkish cult leader, is considered by his followers as the Mahdi.
Ibn Khaldun noted a pattern where embracing a Mahdi claimant enabled unity among tribes and/or a region, often enabled them to forcibly seize power, but the lifespan of such a force was usually limited, as their Mahdi had to conform to hadith prophesies—winning their battles and bringing peace and justice to the world before Judgement Day—which (so far) none have.
Comparative religion
Buddhism
The Mahdi figure in Islam can be likened to the Maitreya figure of Buddhism. Both are prophesied saviors sharing a messianic-like quality, and both are predicted to hold a position of world rulership.
Judaism
Main article: Messiah in JudaismThe prophesied savior duo of the Mahdi and the Messiah in Islam can be likened to the prophesied pair of the two Jewish savior figures, Mashiach ben Yosef and Mashiach ben David, respectively, in the sense that the Islamic Messiah and Masiach ben David take a central eschatological role, while the Mahdi and Mashiach ben Yosef take a peripheral role.

Notes
- D. S. Atema first dated this hadith to between Yazid's death and Ibn al-Zubayr's death. Wilferd Madelung narrowed this down to 684, just after the death of Yazid. Michael Cook and David Cook have contested Madelung's dating. It is nevertheless generally accepted that the hadith is patterned on Ibn al-Zubayr's career. David Cook further states that the latter part of the hadith is totally legendary and is unrelated to Ibn al-Zubayr.
- The leaders of the movement at this stage laid no claim to the imamate as the Mahdi was thought to be the last imam.
- The extinct Zaydi sect of Husayniyya from western Yemen believed in the return of al-Husayn al-Mahdi li-din Allah (d. 1013) as the Mahdi.
