Al-Fadl ibn Salih

[2] In 755, al-Fadl led the pilgrim caravan destined for Mecca and Medina for the annual hajj.

In 775, he was appointed governor of the region of al-Jazira north of Damascus by the Abbasid caliph al-Mahdi.

Al-Fadl returned to Damascus following his trip to Jerusalem in 780 where he accompanied al-Mahdi as part of his entourage.

[2] It was around this time when he was deposed as governor of al-Jazira and replaced by Abd al-Samad ibn Ali.

[5] His governance only lasted one year and when al-Hadi succeeded his father to the Caliphate in 786, he was relieved from his position.

The Bayt al-Mal treasury dome was built under Fadl ibn Salih's orders in 789
