Moslem general, born in Mecca. He was in command of the Koreish cavalry at the battle of Ohod, when Mohammed was defeated; but being converted to the faith in 629, he served under the Caliphs from that time. He led the Moslem forces in northwestern Arabia, and won the battle of Yermouk, which caused Heraclius to abandon Syria in 636, and captured Mecca in 635. He was disliked by the Caliph Omar, and passed his last years in disgrace at Enusa, where he died in 642.
