Jermaine Jackson
The Jackson brother had a solid run of R&B hits in the ’70s and ’80s. In 1989, after a trip to Bahrain, Jermaine converted to Islam. Legally changing his name to Mohammad Abdul Aziz, Jackson later revealed during his appearance on the reality show “Big Brother” that he hoped to convert his younger brother Michael to Islam, and after MJ’s death said that he believed Michael secretly converted shortly before his passing.
