In Islamic eschatology, the Mahdi (Arabic: مهدي, ISO 233: mahdī "guided one") is the prophesied redeemer of Islam who will rule for seven, nine, or nineteen years (according to differing interpretations) before the Day of Judgment (yawm al-qiyamah / literally, the Day of Resurrection) and will rid the world of evil.
There is no explicit reference to the Mahdi in the Qu'ran, but references to him are found in hadith (the reports and traditions of Muhammad's teachings collected after his death). According to Islamic tradition, the Mahdi's tenure will coincide with the Second Coming of Jesus Christ (Isa), who is to assist the Mahdi against the Masih ad-Dajjal (literally, the "false Messiah" or Antichrist). Differences exist in the concept of the Mahdi between Sunni Muslims and adherents of the Shia tradition. For Sunnis, the Mahdi is Muhammad's successor who is yet to come. For most Shia Muslims, the Mahdi was born but disappeared and will remain hidden from humanity until he reappears to bring justice to the world, a doctrine known as the Occultation. For Twelver Shia, this "hidden Imam" is Muhammad al-Mahdi, the Twelfth Imam.
Throughout history, various individuals have claimed to be the Mahdi. These have included Muhammad Jaunpuri, founder of the Mahdavia sect, the Báb (Siyyid Ali Muhammad) founder of Bábism, Muhammad Ahmad, who established the Mahdist state in Sudan in the late 19th century and Mirza Ghulam Ahmad, founder of the Ahmadiyya sect.

There is a lack of evidence for a saviour figure, such as the Mahdi, being part of the teachings of Islam during the life of Muhammad (570-632): neither the Quran nor early Hadith collections make explicit reference to the Mahdi. However, within half a century of Muhammad’s death, the figure of the Mahdi was part of Islamic belief. It may be that the concept of the Mahdi was derived from messianic Judeo-Christian beliefs. 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 reestablish the Himyarite kingdom. They also believed that he would eventually conquer Constantinople.
The second civil war (680-692) marks the true birth of the concept of the Mahdi as a messianic figure. The term Mahdi was first used in this sense during the rebellion of Al-Mukhtar in the 680s in reference to Muhammad al-Hanafiyyah. It seems likely that the attribution of messianic qualities to the Mahdi originated from two of the groups supporting al-Hanafiyyah: southern Arabian settlers and local recent converts in Iraq. They became known as Kaysanites, and introduced what later became two key aspects of the Shia's concept of the Mahdi. The first was the notion of return of the dead, particularly of the Imams. The second was that after al-Hanafiyyah's death they believed he was, in fact, in hiding in the Razwa mountains near Medina. This later developed into the doctrine known as the Occultation.
The Mahdi appeared in early Shi’ite narratives, spread widely among Shi’ite groups and became dissociated from its historical figure, Muhammad al-Hanafiyyah. By the time of the Abbasid Revolution in the year 750, Mahdism was already a known concept. Evidence shows that the first Abbasid caliph assumed the title of "the Mahdi" for himself. Many traditions were introduced to support political interests, especially Anti-Abbassid sentiments.
During the 10th century, based on these earlier beliefs, the doctrine of Mahdism was extensively expanded by Al-Kulayni, Ibrahim al-Qumi and Ibn Babwayhi. In particular, in the early 10th century, the doctrine of the Occultation, which declares that the Twelfth Imam did not die but was concealed by God from the eyes of men, was expounded. The Mahdi became synonymous with the "Hidden Imam" who was thought to be in occultation awaiting the time that God has ordered for his return. This return is envisaged as occurring shortly before the final Day of judgment. In fact, the concept of the "hidden Imam" was attributed to several Imams in turn.
The Sunnis view the Mahdi as the successor of Muhammad, but, unlike most Shia Muslims, do not believe the Mahdi has already been born. The Mahdi is expected to arrive to rule the world and to reestablish righteousness.
References interpreted in hadith
The Mahdi is frequently mentioned in Sunni hadith as establishing the caliphate. Among Sunnis, some believe the Mahdi will be an ordinary man. The following Sunni hadith make references to the Mahdi:
- Muhammad is quoted as saying about the Mahdi:
His name will be my name, and his father’s name my father’s name
Even if the entire duration of the world’s existence has already been exhausted and only one day is left before Doomsday, Allah will expand that day to such length of time as to accommodate the kingdom of a person from my Ahlul-Bayt who will be called by my name. He will fill out the earth with peace and justice as it will have been full of injustice and tyranny (by then). 
- Umm Salama, a wife of Muhammad, is quoted as saying that;
His [the Mahdi's] aim is to establish a moral system from which all superstitious faiths have been eliminated. In the same way that students enter Islam, so unbelievers will come to believe.
When the Mahdi appears, Allah will cause such power of vision and hearing to be manifested in believers that the Mahdi will call to the whole world from where he is, with no postman involved, and they will hear and even see him.
- Abu Sa`id al-Khudri is quoted as saying:
The Messenger of Allah said: "He is one of us".
The Messenger of Allah said: "The Mahdi is of my lineage, with a high forehead and a long, thin, curved nose. He will fill the earth with fairness and justice as it was filled with oppression and injustice, and he will rule for seven years.
The Messenger of Allah said: "At the end of the time of my ummah, the Mahdi will appear. Allah will grant him rain, the earth will bring forth its fruits, he will give a lot of money, cattle will increase and the ummah will become great. He will rule for seven or eight years.
- At-Tirmidhi reported that Muhammad said:
The Mahdi is from my Ummah; he will be born and live to rule five or seven or nine years. (If) one goes to him and says, "Give me (a charity)", he will fill one’s garment with what one needs.
- At-Tirmidhi reported that Muhammad said:
The face of the Mahdi shall shine upon the surface of the Moon.
A typical modernist in his views on the Mahdi, Abul Ala Maududi (1903–1979), the Pakistani Islamic revivalist, stated that the Mahdi will be a modern Islamic reformer/statesman, who will unite the Ummah and revolutionise the world according to the ideology of Islam, but will never claim to be the Mahdi, instead receiving posthumous recognition as such.
Javed Ahmad Ghamidi writes in his Mizan:
Besides these, the coming of the Mahdi and that of Jesus from the heavens are also regarded as signs of the Day of Judgment. I have not mentioned them. The reason is that the narratives of the coming of the Mahdi do not conform to the standards of hadith criticism set forth by the muhaddithun. Some of them are weak and some fabricated; no doubt, some narratives, which are acceptable with regard to their chain of narration, inform us of the coming of a generous caliph; (Muslim, No: 7318) however, if they are deeply deliberated upon, it becomes evident that the caliph they refer to is Umar ibn Abd al-Aziz who was the last caliph from a Sunni standpoint. This prediction of the Prophet has thus materialized in his personality, word for word. One need not wait for any other Mahdi now.
In Shia Islam, the Mahdi is associated with the belief in the Occultation, that the Mahdi is a "hidden Imam" who has already been born and who will one day return alongside Jesus to fill the world with justice.  The promised Mahdi, who is usually mentioned in Shia Islam by his title of Imam-i ’Asr (the Imam of the "Period") and Sahib al-Zaman (the Lord of the Age), is the son of the eleventh Imam. His name is the same as that of the Prophet of Islam. According to Shia Islam, Mahdi was born in Samarra in 868 and until 872 when his father was martyred, lived under his father’s care and tutelage. He was hidden from public view and only a few of the elite among the Shi’ah were able to meet him. 
Shias believe that after the martyrdom of his father he became Imam and by Divine Command went into occultation (ghaybat). Thereafter he appeared only to his deputies (na’ib) and even then only in exceptional circumstances. 
In Shias' perspective, Mahdi chose as a special deputy for a time Uthman ibn Sa’id ’Umari,one of the companions of his father and grandfather who was his conﬁdant and trusted friend. Through his deputy Mahdi would answer the demands and questions of the Shias. After Uthman ibn Sa’id, his son Muhammad ibn Uthman Umari was appointed the deputy of him. After the death of Muhammad ibn Uthman, Abu’l Qasim Husayn ibn Ruh Nawbakhti was the special deputy, and after his death Ali ibn Muhammad Simmari was chosen for this task.
A few days before the death of Ali ibn Muhammad Simmari in 939 an order was issued by Mahdi stating that in six days Ali ibn Muhammad Simmari would die. Henceforth the special deputation of the Imam would come to an end and the major occultation (ghaybat-i kubra) would begin and would continue until the day God grants permission to the Imam to manifest himself.
In Shia view, the occultation of Mahdi is, therefore, divided into two parts: the ﬁrst, the minor occultation (ghaybat-i sughra) which began in 872 and ended in 939, lasting about seventy years; the second, the major occultation which commenced in 939 and will continue as long as God wills it. In a hadith upon whose authenticity Shia and Sunni agree, Muhammad has said, "If there were to remain in the life of the world but one day, God would prolong that day until He sends in it a man from my community and my household. His name will be the same as my name. He will ﬁll the earth with equity and justice as it was ﬁlled with oppression and tyranny."  
Shias believe that the arrival of the Mahdi will be signalled by the following portents:
- The vast majority of people who profess to be Muslim will be so only in name despite their practice of Islamic rites and it will be they who make war with the Mahdi.
- Before his coming will come the red death and the white death, killing two thirds of the world's population. The red death signifies violence and the white death is plague. One third of the world's population will die from the red death and the other third from the white death.
- Several figures will appear: the one-eyed Antichrist (Masih ad-Dajjal), the Al-Harth, Al-Mansur, Shuaib bin Saleh and the Sufyani.
- There will be a great conflict in the land of Syria, until it is destroyed.
- Death and fear will afflict the people of Baghdad and `Iraq. A fire will appear in the sky and a redness will cover them.
Shia traditions also state that the Mahdi be "a young man of medium stature with a handsome face" and black hair and beard. "He will not come in an odd year [...] will appear in Mecca between the corner of the Kaaba and the station of Abraham and people will witness him there.
References interpreted in hadith
- Muhammad is reported in hadith to have said:
The dominion (authority) of the Mahdi is one of the proofs that God has created all things; these are so numerous that his [the Mahdi's] proofs will overcome (will be influential, will be dominant) everyone and nobody will have any counter-proposition against him.
People will flee from him [the Mahdi] as sheep flee from the shepherd. Later, people will begin to look for a purifier. But since they can find none to help them but him, they will begin to run to him.
When matters are entrusted to competent [the Mahdi], Almighty God will raise the lowest part of the world for him, and lower the highest places. So much that he will see the whole world as if in the palm of his hand. Which of you cannot see even a single hair in the palm of his hand?
In the time of the Mahdi, a Muslim in the East will be able to see his Muslim brother in the West, and he in the West will see him in the East.
The Master of the Command was named as the Mahdi because he will dig out the Torah and other heavenly books from the cave in Antioch. He will judge among the people of the Torah according to the Torah; among the people of the Gospel according to the Gospel; among the people of the Psalms in accordance with the Psalms; among the people of the Qur'an in accordance with the Qur'an.
- Ja'far al-Sadiq, the Sixth Imam, made the following prophecies:
Abu Bashir says: When I asked Imam Ja'far al-Sadiq, "O son of the Messenger of God! Who is the Mahdi (qa'im) of your clan (ahl al-bayt)?", he replied: "The Mahdi will conquer the world; at that time the world will be illuminated by the light of God, and everywhere in which those other than God are worshipped will become places where God is worshiped; and even if the polytheists do not wish it, the only faith on that day will be the religion of God.
Sadir al-Sayrafi says: I heard from Imam Abu Abdullah Ja'far al-Sadiq that: Our modest Imam, to whom this occultation belongs [the Mahdi], who is deprived of and denied his rights, will move among them and wander through their markets and walk where they walk, but they will not recognize him ().
Abu Bashir says: I heard Imam Muhammad al-Baqr say: "He said: When the Mahdi appears he will follow in the path of the Messenger of God. Only he [the Mahdi] can explain the works of the Messenger of God.
The face of the Mahdi shall shine upon the surface of the Moon.
According to the Twelver Shia, the main goal of the Mahdi will be to establish an Islamic state and to apply Islamic laws that were revealed to Muhammad. The Mahdi is believed to be the Twelfth Imam, Muhammad al-Mahdi. they believe that the Twelfth Imam will return from the Occultation as the Mahdi with "a company of his chosen ones," and his enemies will be led by Antichrist and the Sufyani. The two armies will fight "one final apocalyptic battle" where the Mahdi and his forces will prevail over evil. After the Mahdi has ruled Earth for a number of years, Isa will return.
For the Sevener Ismāʿīlī, the Imāmate ended with Isma'il ibn Ja'far, whose son Muhammad ibn Ismail was the expected Mahdi that Ja'far al-Sadiq had preached about. However, at this point the Ismāʿīlī Imāms according to the Nizari and Mustaali found areas where they would be able to be safe from the recently founded Abbasid Caliphate, which had defeated and seized control from the Umayyads in 750 AD.
Other sects and religions
In Ahmadiyya belief the terms "Messiah" and "Mahdi" are synonymous terms for one and the same person. Like the term Messiah which, among other meanings, in essence means being anointed by God or appointed by God the term "Mahdi" means guided by God, thus both imply a direct ordainment and a spiritual nurturing by God of a divinely chosen individual. According to Ahmadiyya thought, Messiahship is a phenomenon, through which a special emphasis is given on the transformation of a people by way of offering suffering for the sake of God instead of giving suffering (i.e. refraining from revenge). Ahmadi Muslims believe that this special emphasis was given through the person of Jesus and Mirza Ghulam Ahmad  among others.
These Muslims hold that the prophesied eschatological figures of various religions, the coming of the Messiah and Mahdi in fact were to be fulfilled in one person who was to represent all previous prophets.
Bábí Faith and Bahá'ís
Alí Muḥammad Shírází (20 October 1819 – 9 July 1850), claimed to be the Mahdi on 24 May 1844, taking the name Báb (Arabic: باب / English: Gate) and thereby founding the religion of Bábism. He was later executed by firing squad in the town of Tabriz. His remains are currently kept in a tomb at the Bahá'í World Centre in Haifa, Israel.
The Báb is considered the forerunner of Bahá'u'lláh (pronounced ba-haa-ol-laa / Arabic: بهاء الله / English: Glory of God), and both are considered prophets of the Bahá'í Faith. The declaration by the Báb to be the Mahdi is considered by Baha'is to be the beginning of the Bahá'í calendar.
The Mahdavia sect, founded by Muhammad Jaunpuri commonly known as Nur Pak claimed to be the Mahdi in Mecca, in front of Kaaba (between rukn and maqam) in the Hijri year 901(10th Hijri), and is revered as such by Mahdavia. He was born in Jaunpur, traveled throughout India, Arabia and Khorasan, where he died at the town of Farah, Afghanistan at the age of 63. The Mahdavi regard Jaunpuri as the Imam Mahdi, the Caliph of Allah and the second most important figure after the Islamic prophet Muhammad.
In Dasam Granth, the Sikh scripture attributed to the tenth Sikh guru Guru Gobind Singh prophesizes the Mahdi (referred to as "Mahdi Meer") to be born for a purpose of defeating Kalki, an avatar of Vishnu. As Kalki becomes egoistic and begins referring to himself as the Almighty, the powerful Mahdi will slay him and rule the world. However later he too will become egoistic and will begin referring to himself as god. The unmanifested Brahman (Supreme God) will kill Mahdi by creating an insect, which goes into Mahdi's ear and kills him.
Persons claiming to be the Mahdi
The following individuals (or their adherents on their behalf) have claimed to be the Mahdi:
- The first historical reference to a movement using the name of Mahdi is al-Mukhtar's rebellion against the Umayyad caliphate in 686 CE, almost 50 years after Muhammad's death. Al-Mukhtar claimed that Muhammad ibn al-Hanafiyyah, a son of the fourth caliph and first Shia Imam, Ali, was the Mahdi and would save the Muslim people from the rule of the Umayyads. Ibn al-Hanifiyyah himself was not actively involved in the rebellion, and when the Umayyads successfully quashed it, they left him undisturbed.
- Muhammad Jaunpuri (1443–1505), founder of the Mahdavi sect. (See above.)
- Ahmed ibn Abi Mahalli (1559–1613), from the south of Morocco, was a cadi and religious scholar who proclaimed himself mahdi and lead a revolution (1610–13) against the reigning Saadi dynasty.
- The Báb, (Siyyid Ali Muhammad) claimed to be the Mahdi in 1844 A.D (in the year 1260 A.H), thereby founding the religion of Bábism. He was later executed by firing squad in the town of Tabriz. His remains are currently kept in a tomb at the Bahá'í World Centre in Haifa, Israel. The Báb is considered the forerunner of Bahá'u'lláh, and both are considered prophets of the Bahá'í Faith. The declaration by the Báb to be the Mahdi is considered by Baha'is to be the beginning of the Bahá'í calendar.
- Muhammad Ahmad (1845–1885), a Sudanese Sufi sheikh of the Samaniyya order, declared himself Mahdi in June 1881 and went on to lead a successful military campaign against the Turko-Egyptian government of Sudan. Although he died shortly after capturing the Sudanese capital, Khartoum, in 1885, the Mahdist state continued under his successor, Abdallahi ibn Muhammad, until 1898, when it fell to the British army following the Battle of Omdurman.
- Mirza Ghulam Ahmad (1835–1908) claimed to be both the Mahdi and the second coming of Jesus in the late nineteenth century in British India and founded the Ahmadiyya religious movement in 1889. (See above.)
- Muhammad bin abd Allah al-Qahtani was proclaimed the Mahdi by his brother-in-law, Juhayman al-Otaibi, who led over 200 militants to seize the Grand Mosque in Mecca in November 1979. The uprising was defeated after a two-week siege in which at least 300 people were killed.
