Abū Isḥāq Ibrāhīm al-Mawṣilī (742–804), was a Persian Arabic-language singer who was settled in Kufa. In his early years his parents died and he was trained by an uncle. Singing, not study, attracted him, and at the age of twenty-three he fled to Mosul, where he joined a band of wild youths.
After a year he went to Rayy, where he met an ambassador of the caliph al-Mansur, who enabled him to come to Basra and take singing lessons. His fame as a singer spread, and the caliph al-Mahdi brought him to the court. There he remained a favorite under al-Hadi, while Harun al-Rashid kept him always with him until his death, when he ordered his son al-Ma'mun to say the prayer over his corpse.
Ibrahim, as might be expected, was no strict Muslim. Two or three times he was knouted and imprisoned for excess in wine-drinking, but was always taken into favor again. His powers of song were far beyond anything else known at the time. Two of his pupils, his son Ishaq al-Mawsili and the freedman slave Mukhariq, attained celebrity after him.
