Read the German religion historian Christian Luxenberg’s (not his real name for obvious reasons!) book - The Syro-Arama8c Reading of the Koran. He argues i think successfully that the Koran is a deliberate misreading\rendering in Arabic of early Eastern Gnostic Christian liturgical writings. If you read it in Syro-Aramic it’s a different book. Much of the weird grammar constructs and strange theology go away. Now that doesn’t make this literary package standard Christian but certainly makes it radically different from what Islam claims.

My understanding has been that if you read the dag hamadi scrolls that were discovered about 1946 or so—that these banned gnostic gospils give a version of Jesus that looks very much like Mohammed’s version of Jesus.
Is your point the same?
