In 755, al-Fadl led the pilgrim caravan destined for
Mecca and
Medina for the annual
hajj. He became governor of
Jund Dimashq (whose principal city was
Damascus) in 766 and three years later he added
Jund Qinnasrin (whose principal city was
Aleppo) to his domain during the reign of the caliph
al-Mansur. In 775, he was appointed governor of the region of
al-Jazira north of Damascus by the Abbasid caliph
al-Mahdi. He moved to al-Jazira the same year. Al-Fadl returned to Damascus following his trip to
Jerusalem in 780 where he accompanied al-Mahdi as part of his entourage. It was around this time when he was deposed as governor of al-Jazira and replaced by
Abd al-Samad ibn Ali. Al-Fadl was sent along with a large army to quell a rebellion in
Egypt in 785. After defeating the rebels at Buwit, al-Mahdi appointed him governor of
al-Fustat in Egypt. He established the soldiers' barracks and the congregational mosque of al-Askar and during his tenure the cities of
al-Askar and
al-Fustat merged into one large city. His governance only lasted one year and when
al-Hadi succeeded his father to the Caliphate in 786, he was relieved from his position. Upon his return to Syria in 789, he had the doors of the
Umayyad Mosque replaced and built the famed
Bayt al-Mal treasury dome to house the mosque's funds. Al-Fadl was also responsible for the construction of the eastern Dome of the Clock, which was built in 780. ==References==
