Is the Nation of Islam considered a Post-Islamic Religion?

Answer 1

No. The Nation of Islam is an African-American Religion, not a derivative of Islam.

Definition of Post-Islamic Religion

Post-Islamic Religions are typically defined as religions that developed as outgrowths of Islam that changed and developed one or more of the core teachings of Islam to the point where they are often considered heresy by mainstream Muslims and will often declare themselves as a distinct faith outside of Islam. However, these religions share most of Islam's fundamental teachings and consider the Qur'an a holy book. Since these religions tend to have few adherents and those adherents stay primarily in the Middle East, they are often overlooked by people who talk about the five major religions: Judaism, Christianity, Islam, Hinduism, and Buddhism. Even combined, they represent less than 25 million people.

The Post-Islamic Faiths include Baha'i, Druze, Azali, Yezidi, Yarsan, Alawite, Alevi, and Ahmadiyya. Some of these religions are occasionally considered Islamic, especially the latter three, but more often they are not.

Nation of Islam

The Nation of Islam is not a Post-Islamic Religion, but an African-American religion. The African-American faiths strike a common tone, typically of black supremacy either by birth or by merit and use the texts of pre-existent religions to buttress those claims. This is visible in the Black Israelite Churches, Rastafarianism, and the Nation of Islam. It is for this reason that these faiths bear little in common with the non-African-American faiths that use the same holy texts.
