Abūʾl-Qāsim ʿĪsā ibn al-Ẓāfir (Arabic: أبو القاسم عيسى بن الظافر; 1149–1160), better known by his regnal name al-Fāʾiz bi-Naṣr Allāh (الفائز بنصر الله), 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.
