Prophet my ass. He was a late stage schizophrenic who went off to the mountains, heard voices, and concluded it must be angels (Allah never communicates directly with humans, he is to Other that he uses angels...its in the escape clause of his contract). Modern schizophrenics are typically enamored with religion and also hear angels, devils, Jimmy Carter, Kim Jong-un, the arch-angel Gabriel, and funny talking frogs (think the Loony-Tune's cartoon with the frog singing but only when the owner cannot make any money off him).
The entire situation reminds me of the joke where a fellow advertises to sell his talking dog. A prospective buyer goes to the fellow's house and is told the dog is in the bedroom. So the guy goes in and asks the dog to speak. The dog greets him, "How ya doing?". And guy is awed and asks the dog what he's been doing all these years. The dog props himself on an elbow and says that he was involved in the WTC rescue effort and saved 20 people. He also was sent up in the space shuttle to perform science experiments and found a new form of matter. And he helped fly helicopters after Hurricane Katrina, saving people. The guy is totally blown away, so he goes out into the other room and asks the fellow why he's selling his talking dog. The guy says in a loud voice so the dog can hear "BECAUSE HE'S A BIG LIAR!"
