While the group calls its followers Muslims, in reality, they have very little to do with the faith of Islam. Islam maintains universal brotherhood, the NOI says that Islam is for blacks only. Islam teaches that prophethood ended with Muhammad ibn Abdullah, more than 1400 years ago. The NOI teaches that Farrakhan's teacher, Elijah Muhammad, is the last prophet. Islam teaches principles of spiritual and moral decorum such prayer, fasting, charity, pilgimage, etc., Elijah Muhammad cast these out or altered them beyond recognition.
Racism has very little to do with the issue.
Sure, racism is contrary to Islamic principles and Islam rejects it. However, the deviation of Elijah Muhammad and Louis Farrakhan are MUCH more serious than racism. It is the sin which Allah DOES NOT forgive. Let me say very clearly, that there is NO ideology on the face of this earth which could be farther from Islam than that of Louis Farrakhan.
