I'm just gonna assume you don't know. The Nation of Islam is not Islamic. Muslims believe that there is one true god, no god but god, and any claimed earthly manifestation is a falsehood. The NOI believes that their founder, Wallace Fard Muhammad, was god himself come in the form of man to Detroit in 1930. He disappeared in 1934. Muslims believe that the prophet Mohammad (blessings and peace be upon him)was the final prophet of god; there have been no true prophet since. The NOI believes that Wallace Fard Muhammad, god in the flesh, appointed the most honorable Elijah Muhammad as his prophet. These quirky beliefs alone would make the NOI an odd, but ultimately harmless, religious sect of little note. But it is their final heresy that is most impactful.
Islam teaches that god made all the numerous tribes of the earth, not to separate each other and bicker, but to know each other and unify. Any student of events, past and historic, know that this has not always been a peaceful Islamic tenant in practice, but nobody can deny that the religion seeks to make converts of anyone and everyone, bringing as many tribes into the fold as possible. The NOI teaches that there is a racial hierarchy. The African race is the noblest and best race of mankind; the white race is not even human. In this, we find the Nation of Islam's true mission: to create a separate black state, in this country or elsewhere, at the expense of the white devil. They are modern day segregationists, they run counter to all that America values, and they have political influence.
