"The Almighty Black P. Stone Nation is an American street gang founded in Chicago, estimated to have more than 100,000 members. 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" (or simply El Rukn, Arabic for "the pillar" or "the foundation").They eventually started describing themselves as Orthodox Sunni Muslims."
