The surviving records on the internal history and rulers of the Emirate of Crete are very fragmentary. He is tentatively identified as a son of the seventh emir, Ahmad ibn Umar, and as the great-great-grandson of the conqueror of Crete and founder of the emirate, Abu Hafs Umar. He is believed to have reigned from c. 943 to c. 949, succeeding his brother Shu'ayb, and being succeeded by his nephew, Shu'ayb's son, Abd al-Aziz.
