At some point the Arabs will claim King David was a Palestinian....
well, with all the inter-mixing of blood, I’d be surprised if some west bank Arabs do not have Jewish and thereby Davidic blood
Why not, since it would make sense to them? They already claim he was a Muslim, when they admit to his existence.
Oh, and Adam, Noah, Abraham, Ishmael (but not so much Isaac), Moses, and even Jesus were Muslims, too.
Doctrinally, Mad Mo didn't "begin" Islam; he, as the "Final Prophet" only reiterated the "correct" and "pure" message that "the Peoples of the Book" had lost or distorted over the ages. He was simply calling (yeah, right; "calling" with a sword & lies) people "back" to the "true" (Satan inspired) religion of old.
It all goes back to their claim that Ishmael, not Isaac, was "the child of the Covenant of Abraham; that Jacob/Israel and The Children were usurpers.
