Ali emerged into prominence as an able fiscal administrator and deputy to his older brother Ahmad.

Eventually he came to lead one of the two major and rival court factions during al-Muqtadir's caliphate, the Banu'l-Furat, the other being the group of officials around the commander-in-chief Mu'nis al-Muzaffar and the vizier Ali ibn Isa al-Jarrah. He played an important role in the selection of al-Muqtadir as caliph in 908, going on to serve as vizier in 908–912, during which time he succeeded in re-incorporating Fars into the Caliphate and to restore a measure of authority over the Sajids of Adharbayjan.

After a second tenure in 917–918 he was imprisoned by his successor, and was released in 923, becoming vizier for the third and last time soon after. His brutality towards his rivals during his third tenure, coupled with military failures against the Qarmatians, caused his deposition and execution, along with his son al-Muhassin, on 18 July 924.
