For example the religious group "Nation of Islam" believes that Yakub, a black scientist, crated the white race / ethnic group and tricknology a few thousand years ago
The Nation of Islam are Muslims. They would be considered theologically descended from the Abrahamic line of religions. They would certainly not be considered a "tribe". And they take their creation mythology from the Koran.
I think you may be talking about the ADOS people who believe all sorts of conspiracy theories like that, but are not a religious group at all. However they do believe black Christians and black Muslims are following the "white man's" religions. In any case, their beliefs would mean the ADOS nutjobs are technically "crackpots", as the initial post indicated, rather than a "tribe".

Not really, and most Muslims would dispute that the Nation of Islam is Islam.
The Nation of Islam is essentially a newly invented religion from the early 1900s. It has its own extensive Sci-Fi mythology (including the Yakub story) that is pretty much entirely different from Islam, though it borrows some aspects of Islam. It's heavily influenced by Black Nationalism and Pan-Africanism.
