The Almighty Black P. Stone Nation often abbreviated as (BPS, BPSN, Black Peace Stones, Black P. Stones, Stones, or Moes) 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" (or simply El Rukn, Arabic for "the pillar" or "the foundation").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.
