Mustaali

The Musta ʿ Israel or Musta ʿ lī (Arabic مستعلي ) are Ismaili Muslims, whose name comes from the fact that they consider the Fatimid ruler al - Musta'li as the nineteenth Imam or the ninth caliph and legitimate successor of his father, al - Mustansir, . In contrast, the Nizāriyya - Muslims believe - today under the leadership of the Aga Khan - that Musta'lis older brother, Nizar the rightful nineteenth Imam would.

This split the Ismailis in Egypt in fractions of the Nizari and Musta'lis occurred in the year 1094th

After the death of the 8th Fatimid Caliph Mustansir († 1094 ), the succession was disputed. The Regent al - Afdal Shahanshah sat Mustansirs younger son Al- Musta'li than 9 caliph on the throne. In contrast, defended the elder son Nizar, however was defeated and died in prison. This dispute led to the splitting into the two branches of Musta'liten and the Nizari that exist to this day.

The Musta'liyya be as Tayyibiten or Ṭayyibī (Arabic طيبي ) called after the last recognized by them ( twenty-first ) Imam, Abu l -Qasim at- Tayyib, the son of Al -Amir ( 1096-1130 ), the 20th Imam. Originally distinction was made between the Tayyibiten (al- Ṭayyibiyya ) and the Hafiziten (al- Ḥāfiziyya ) that recognize al - Hafiz, the Fatimid rulers of Egypt between 1130-1169 as legitimate Imam, and not Tayyib Abi l -Qasim. The Hafiziten lost all support after the downfall of the Fatimid dynasty; today Musta'liyya are all Tayyibiten.

The majority of Musta'lis believed that at- Tayyib had disappeared, but that he was staying in a concealment as the Mahdi, as originally believed the Ismailis of Muhammad ibn Ismail.

The largest Musta'liten group is that of the Bohras, of which encountered mainly in India group of Dawoodi Bohras is the largest.
