ISLAM at its origin and roots came out of Ishmael, son of Abraham, with Hagar. Sara, wife of Abraham, then conceived and delivered him a son, Issac.
Hagar, with her son, were then banished to the desert. God saved them, but pronounced her son would be a people, an ever warring nation
There's really no viable argument against that history. The proofs are readily available.
Ishmael as patriarch was a long time before Mohammed.
