With that said, it's important to know that the 'Nation of Islam' is considered 'heretical' by orthodox Islam. It contradicts Islam's teachings on theology, history, etc. Neither Sunnis nor Shia's hold NOI beliefs, and comparing the NOI to 'Islam according to Muhammad' is akin to calling a Jehovah's Witness a 'Christian.'
For much more information on the NOI and it's teachings, watch this show that Tony did with Elreta Dodds called, "Is Islam the True Religion of the Black Man?" On a similar note, the follow-up episode was called, "Is Christianity the White Man's Religion?"
