All the Blather That is Islamic Theology

This is not the Flight into Egypt.
This is Abraham Dismissing Hagar and Ishmael 

Discrepancies in Mohammedan theology are numerous, one being that originally Islam was not called Islam at all but rather what it actually was - Mohammedanism, meaning the religion of Muhammad, not God.

That being said, one major error in all the blather that is Islamic "theology" is this: If Muhammad was a prophet sent from God, why would God choose an Arab descended from a Hebrew?

Muslims believe that Islam is the PURE word of God, so why would God not have chosen a PURE Arab to dispense the PURE Quran to the world? Muhammad was not a pure Arab because he was descended from Ishmael, or so the story goes. Ishmael's father of course was Abraham, Abraham was a Hebrew, and while in his father's household, Ishmael would have practiced his father's Hebrew religion.
