- (fl. 8th cent)Persian religious leader. A disciple of Abu Issa al-Isfahani, he lived in Hamadan. He was influenced by the doctrines of Islamic Sufism: he maintained that he was a prophet, advocated a mystical interpretation of the Torah, and argued that all religious symbols are allegories; he also supported the prohibition of wine and animal food introduced by the Issavites. A group of disciples grew up around him, which became known as the Yugdhanites.
