Layth ibn Tarif
Layth ibn Tarif was an 8th-century freedman commander and governor for the Abbasid Caliphate.Biography
misidentified him as the son of Nasr ibn Sayyar, the last Umayyad governor of Khurasan., but according to the Kitab al-Aghani and other sources, Layth and his brother Mu'alla were the sons of a certain Tarif, a slave or client of the Abbasid caliph al-Mansur. Layth and his brother were purchased as slaves by al-Mansur and given to his heir al-Mahdi, who set them free.
Layth is first mentioned as commanding an army against the king of Farghana under al-Masnur, while al-Mahdi sent him against the Iranian rebel al-Muqanna. Later al-Mahdi appointed him as governor of Sind. He was recalled during the brief reign of al-Hadi, but reinstated to the post by Harun al-Rashid. Either he or Layth ibn al-Fadl were governors of Dinawar in 796/7.
