Khadijah Farrakhan, the longtime wife of Nation of Islam leader Louis Farrakhan and the organisation’s “First Lady,” has died at age 90. Multiple outlets report that the Nation of Islam announced her death in a statement that included a Quranic verse, saying she “returned to Allah.” The reports do not disclose a cause of death.

Khadijah Farrakhan, often referred to affectionately as “Mother Khadijah,” worked alongside her husband for decades as the Nation of Islam’s religious and sociopolitical activities expanded. She is described as having remained by Louis Farrakhan’s side throughout his rise within the movement and became First Lady after he took leadership in the early 1980s.

The couples’ marriage began in 1953, and both converted to Islam in the early 1950s after Louis Farrakhan was introduced to the Nation of Islam by fellow musician Rodney Smith, according to accounts cited by several outlets. One outlet also notes that Khadijah Farrakhan addressed the Million Women March in 1997.

Funeral arrangements and further details are not yet reported as announced by the Nation of Islam. The couple had nine children, eight of whom reportedly survive her.
