Khadijah Farrakhan, longtime wife of Nation of Islam leader Louis Farrakhan, died Saturday, the Nation of Islam has announced. She was 90.

The Nation of Islam leader who was recently banned from Facebook spoke Thursday in a wide-ranging sermon that hit upon some of the anti-Semitic and black nationalist themes he has come to be known for.

The Rev. Michael Pfleger invited the controversial minister to speak at St. Sabina Catholic Church days after Facebook banned Louis Farrakhan and several other “dangerous individuals.”
