Al-Faiz

Abūʾl-Qāsim ʿĪsā ibn al-Ẓāfir, better known by his regnal name al-Fāʾiz bi-Naṣr Allāh, was the thirteenth and penultimate Fatimid caliph, reigning in Egypt from 1154 to 1160, and the 23rd imam of the Hafizi Ismaili branch of Shi'a Islam. Al-Fa'iz was raised to the throne at the age of five after the murder of his father by the vizier Abbas ibn Abi al-Futuh, and spent his entire life as a puppet of Abbas' successor, Tala'i ibn Ruzzik. Experiencing epileptic seizures, al-Fa'iz died from an episode at the age of eleven, and his nephew, al-Adid, the final Fatimid caliph, succeeded him.
