Born in Detroit, Michigan, the third son of the Nation of Islam leader Elijah Muhammad, Herbert served as a chief adviser to his father until his departure in 1975. He also worked as the chief business manager for the Nation of Islam, and he along with the late Malcolm X founded their weekly newspaper. Herbert was a staunch supporter of his brother, Imam Warith Deen Muhammad, whom he followed into mainstream Islam.
Along with Muhammad Ali and others, Herbert built Masjid Al-Fatir Mosque on the south side of Chicago, Illinois, one of the first Mosques built from the ground by Muslim Americans. Herbert also served as the director and founder of the Muhammad Islamic Foundation, a not-for-profit foundation which also published the noted book 'Prayer and Al-Islam' by Imam Warith Deen Mohammed in 1984. Muhammad managed Muhammad Ali's professional boxing career from 1966 until Ali's ring retirement after losing to Trevor Berbick in December 1981 in the Bahamas in his final comeback attempt. In the face of his close friend's slow physical decline, Herbert continued to superbly manage Ali's affairs until 1991, when their association ended. He died at age 79 in 2008 from complications after open heart surgery at the University of Chicago Medical Center in Chicago. He was survived by his 14 children.
