Тайыб ибн әл-Амир: Таййиби исмаилизмінің жиырма бірінші имамы

Twenty first and last known imam of the Tayyibi Isma'ilis

Abūʾl Qāsim al Ṭayyib ibn al Āmir (أبو القاسم الطيب بن الآمر) was, according to the Tayyibi sect of Isma'ilism, the twenty first imam. The only son of Caliph al Amir bi Ahkam Allah, al Tayyib was an infant when his father was murdered. Amidst the ensuing power struggle, al Tayyib disappeared; modern historians suggest that he died or was secretly killed by one of the rival strongmen. By 1132, his uncle al Hafiz declared himself as the caliph and imam in succession to al Amir. This was not accepted by the Yemeni Isma'ilis, who upheld the rights of al Tayyib. This marked the creation of two rival sects of Musta'li Isma'ilism, the Hafizi one, following al Hafiz, and the Tayyibi one, following al Tayyib. The Tayyibis hold that al Tayyib was rescued from Cairo and brought to safety, but that he and all subsequent Tayyibi imams remained in hiding. The Tayyibi community was instead led by a sequence of 'absolute missionaries' .

Al Tayyib was the only son of the twentieth Fatimid imam caliph, al Amir bi Ahkam Allah, who ruled Egypt from 1101 to 1130. Al Tayyib was born in Cairo in February/March 1130, and immediately, according to one source, designated as heir apparent. Al Amir was assassinated on 7 October of the same year by agents of the rival Nizari sect of Isma'ili Shi'ism.

With only an infant child as potential heir, the dynasty's authority devolved on to al Amir's cousin, Abd al Majid, as the oldest surviving male of the dynasty. What happened next appears to have effectively been a coup: two of al Amir's favourites, Hizar al Mulk Hazarmard (or Jawarmard) and Barghash, who had influence over the army, allied themselves with Abd al Majid, to control the government. Abd al Majid, who may have had his eyes on the caliphate, was to become regent. It is unclear, however, in whose name Abd al Maji's regency was exercised. Most sources report that even the existence of al Tayyib was concealed, and he disappears completely from the record after that. How the existence of a child, whose birth had been accompanied by public celebrations and proclamations, was so effectively concealed is unknown. Modern scholars speculate that al Tayyib may have died in infancy, possibly even before his father; but at least one contemporary anonymous Syrian source maintains that he was murdered on Abd al Majid's orders. As a result of this silence in official sources, al Tayyib's existence was doubted by some early scholars of Isma'ilism in the 20th century. His historicity is now considered as established, based on several points: surviving reports of festivities ordered by al Amir to celebrate his birth survive, scattered references to him in 12th century historians, and a surviving example, sent to the Yemeni queen Arwa al Sulayhi, of the letters sent to friendly rulers to announce the event.

Instead of al Tayyib, the new regime maintained that al Amir had left a pregnant concubine, and that the caliph, having dreamed of his impending death, had declared this unborn child to be a son and his designated successor, thus effectively bypassing al Tayyib. What came of this pregnancy is likewise unclear, as different sources report that the concubine either bore a daughter or that the foetus could not be found, or that Abd al Majid killed the baby soon after. The only dissenting account is that of the 15th century Tayyibi leader and historian Idris Imad al Din, who explicitly claims that Abd al Majid took office as regent for al Tayyib. Whatever the truth, the new regime did not last long, as the army mutinied and installed Kutayfat as vizier. Initially Kutayfat retained Abd al Majid as regent, but the latter was de facto a prisoner; soon Kutayfat proclaimed the dynasty deposed altogether, and abandoned Isma'ilism as the state religion in favour of a vaguely Twelver form of Shi'ism with himself as vicegerent of a hidden imam. The historian Heinz Halm considers it likely that Kutayfat at this point eliminated al Tayyib. Kutayfat was assassinated by Fatimid loyalists in December 1131, and Abd al Majid was released from his prison. Abd al Majid initially resumed ruling as a regent, but on 23 January 1132 he proclaimed himself imam and caliph in succession to al Amir with the regnal name of al Hafiz. Al Hafiz's highly irregular accession and claims to the imamate were largely accepted by the Isma'ili faithful in the Fatimid domains in Egypt, Nubia, and the Levant, but rebuffed by some communities. Most notably, this was the case in the only other major Isma'ili realm, Yemen, where Queen Arwa upheld the rights of al Tayyib, while the subordinate regional dynasties of the Hamdanids and the Zurayids recognized al Hafiz's claims. Al Hafiz's accession thus produced a major schism in the Musta'li branch of Isma'ilism, between the adherents of the imamate of al Tayyib (the 'Tayyibis') pitted against supporters of al Hafiz and his successors (the 'Hafizis'). The Tayyibis hold that al Tayyib did not die, but that he had been entrusted by al Amir to a certain Ibn Madyan, and that the infant had been hidden by Ibn Madyan and his helpers when Kutayfat came to power. Ibn Madyan was killed by Kutayfat, but his brother in law escaped with al Tayyib, who now went into concealment. Al Tayyib is held to have died while still in concealment, but to have had descendants, who have provided a series of hidden imams that continue to the present day. The public leadership of the Tayyibi community was instead assumed by a succession of 'absolute missionaries' .
