(fl. 9th cent)
Persian Karaite scholar. He lived in Nahavend in Persia, where he established a community that observed Karaite principles and methods of biblical study. He was the first Karaite author to write in Hebrew, and was responsible for the use of the name 'Karaites' to designate the members of the sect (in place of the former 'Ananites').
