Malcolm X was one of the most influential leaders of the NOI and, in accordance with NOI doctrine, advocated the complete separation of blacks from whites.[28] He left the NOI after being silenced for 90 days (due to a controversial comment on the John F. Kennedy assassination), and proceeded to form Muslim Mosque, Inc. and the Organization of Afro-American Unity before his pilgrimage to Mecca and conversion to Sunni Islam. He is viewed as the first person to start the movement among African Americans towards Sunni Islam.
