Mokanna

Mokanna, Hakim ben Allah (" the Veiled prophet of Khorassan"), so called from the veil which he had flung over his features "To hide from lmtnan sight His dazzling brow, till man could hear its light." Mokanna claimed to be an incarnation of the Divine Being, and became the leader of a numerous sect, but was finally defeated by the Kalif Almahdi, and took poison to escape a worse fate (780 A.D.).
