a Mohammedan doctor of the sect of the Motazelites. The name of Jahed, by which he is generally designated, is only a surname given to him on account of his brilliant eyes. He was thoroughly acquainted with Greek literature. He gained a great many adherents by his writings and eloquence. Among his theological books one is cited. as being composed in favor of Ali, and containing more than a thousand traditions respecting him. The best of his works, according to Ibn-Khallican, who cites but two, is a treatise on animals, probably borrowed largely from Greek writers. Jahed died at Bussora, A.D. 869. See Hoefer, Nouv. Biog.
