Apparently, this is actually what the Nation of Islam really teaches!
If you'd like to know more about the Nation of Islam, you should find a copy of
Zebra, The True Account of the 179 Days of Terror in San Francisco, by Clark Howard, Richard Marck Publishers, New York, © 1979.
It's about several black thugs in San Francisco and Oakland who wanted to become members of the Nation of Islam's Death Angels. Nation of Islam is not what one would call a benign "religion." It's also interesting in the details of how the S.F. Homicide detectives finally caught them as all the murders were random. This was late 1973 and early 1974.
