It funny how someone who has preached against integration and been pro Black for over 50 years,one of his children has a white wife
and I know he mentioned a few of them went to predominately white universities. now he endorses Scientology intermixed with their brand of Islam. 
Ali himself was against race mixing even though he was a product of race mixing himself.
Cassius Marcellus Clay Jr., was born on January 17, 1942, in Louisville, Kentucky.[20] The older of two boys, he was named for his father, Cassius Marcellus Clay Sr., who himself was named in honour of the 19th century abolitionist and politician of the same name. He had a sister and four brothers, including Nathaniel Clay.[21][22] Clay's paternal grandparents were John Clay and Sallie Anne Clay; Clay's sister Eva quoted that Sallie was a native of Madagascar.[23] His father painted billboards and signs,[20] and his mother, Odessa O'Grady Clay, was a household domestic. Although Cassius Sr. was a Methodist, he allowed Odessa to bring up both Cassius and his younger brother Rudolph "Rudy" Clay (later renamed Rahman Ali) as Baptists.[24] He is a descendant of pre-Civil War era American slaves in the American South,
and is predominantly of African-American descent, with Irish, English, and Italian ancestry.[25][26][27]
