Here’s what I know of them. It’s directly from them. I didn’t make this up.
“IN 1931, THE MASTER WAS preaching this Great Truth of salvation when He met a man named Elijah Poole (Muhammad) in Detroit, Michigan. He chose him to be His Divine Representative in continuing this most difficult task of bringing truth and light to His lost and found people. For 3 1/2 years He taught and trained the Honorable Elijah Muhammad night and day into the profound Secret Wisdom of the Reality of God, which included the hidden knowledge of the original people who were the first founders of civilization of our Planet and who had a full knowledge of the Universal Order of Things from the beginning of the Divine Creation.”

They go on to explain who THE MASTER is: (under the heading "What The
Muslims Believe")
“12. WE BELIEVE that Allah (God) appeared in the Person of Master W. Fard Muhammad, July, 1930; the long-awaited “Messiah” of the Christians and the “Mahdi” of the Muslims.”

Since god appointed Elijah Muhammad as his divine representative, in essence Elijah Muhammad is a prophet of god according to the Nation of Islam.
