A) The traditions concerning Imam al-Mahdi

There are many traditions attributed to the Prophet in the books of tradition concerning the identity of al-Mahdi, his family, his epithet (kunya) and his character. The conclusion of these numerous traditions is that al-Mahdi is a descendant of the sons of Fatima27, the daughter of the Prophet; and more particularly, that he is of the progeny of her son al-Husayn.

His colour is similar to that of the Arab, and his body is like the Israelite, and his name and kunya are similar to,the name and kunya of the Prophet28. Moreover some traditions claim that the Prophet said that al-Mahdi's father's name is like the name of the Prophet's grandson, al-Hasan. Below are a number of these traditions.

i) We, the family of ‘Abd al-Muttalib, are the Masters of the inhabitants of Paradise: I, Hamza, Ja’far, ‘Ali, al-Hasan, al-Husayn and al-Mahdi.

ii) Al-Mahdi is from my progeny. His name is similar to mine and his epithet is similar to mine. In his physique and character he looks exactly like me. He will be in a state of occultation and there will be confusion (Hayra) in which people will wander about. Then he will come forth like a sharp, shooting star to fill the earth with justice and equity as it was filled before with injustice and inequity.

iii) Al-Mahdi is from my family (‘itra) from the sons of Fatima. It is worth mentioning that this tradition was reported on the authority of Umm Salama by ‘Ali b. Nufayl, who died in 125/742.

iv) On the authority of Ibn 'Abbas, the Prophet is reported to have said, "How shall Allah destroy a nation whose beginning is myself, whose end is Jesus and whose very centre is al-Mahdi, who will be from my family?

v) The name of al-Mahdi's father is similar to the name of my son al-Hasan.

The conclusion of Osman concerning these traditions seems to be rather forced. "All these hadiths are weak and contradictory (mutadarib), therefore their attribution to the Prophet Muhammad is to be very much doubted.

For the use of the epithet al-Mahdi by numerous Islamic groups, particularly the Zaydites, in their struggle for power during the Umayyad period shows that these traditions were well-known among the Muslims of that period. Moreover, many traditionists from different Islamic sects transmitted these traditions before the downfall of the Umayyads in 132/749, and later they were collected in the books of tradition (hadith).

The earliest of these books was Kitab Sulaym b. Qays, attributed to Sulaym b. Qays al-Hilali, who died between the years 80-90/699-708. He reports many Prophetic traditions concerning al-Mahdi, his occultation and his reappearance.

It appears from these two points that Osman's judgement is somewhat hasty, particularly if one takes into account the fact that Prophetic traditions regarding al-Mahdi were narrated by twenty-six companions of the Prophet. On their authority thirty­-eight traditionists recorded these traditions in their collections of hadith.

The evidence suggests that from the earliest times in Islam there was a belief that the Prophet had given his followers a promise about a man from the progeny of al-Husayn, who would rise in arms in the future to purify Islam from innovation. But political rivalry amongst the Muslims encouraged some people to exploit this hope and to distort these Prophetic traditions in order to use them in their struggle for power.

These traditions only mention that al-Qa’im al-Mahdi will be from the progeny of the Prophet. But there are also other traditions attributed to the Prophet which state that al-Mahdi will, in fact, be the Twelfth Imam.

It is true that Montgomery Watt objects that,

Until al-’Askari died on 1st Jan. 874, there was nothing to make people expect that the number of the Imams would be limited to twelve or that the Twelfth would go into occultation. It follows the theory of the twelve Imams was worked out after 874.

Nevertheless, there is ample proof that traditions claiming a-l­Qa'im would be the Twelfth descendant of the Prophet were in circulation before 874. It is thus necessary to throw light upon these traditions, which were,transmitted by Sunnites and Zaydites as well as Imamites, so that one can see to what extent these traditions were used by the Imamite scholars to support the belief that the Twelfth Imam had not died but was in a state of occultation.
