The Almighty Black P. Stone Nation is an American street gang founded in Chicago. The gang was originally formed in the late 1950s as the Blackstone Rangers. The organization was co-founded by Eugene Hairston and Jeff Fort. In later years, under Fort's leadership, an Islamic faction of the gang emerged, naming themselves the "El Rukn tribe of the Moorish Science Temple of America" . They eventually started describing themselves as Orthodox Sunni Muslims. Jeff Fort changed their fort name from El Rukn Moorish Science Mosque, to El Rukn Sunni Masjid al-Malik.

The Moorish Science Temple of America is an American national and religious organization founded by Noble Drew Ali in the early 20th century. He based it on the premise that African Americans are descendants of the Moabites and thus are "Moorish" by nationality, and Islamic by faith. Ali put together elements of major traditions to develop a message of personal transformation through historical education, racial pride, and spiritual uplift. His doctrine was also intended to provide African Americans with a sense of identity in the world and to promote civic involvement.
