Based on history and bible - Ishmael was the origin of Islam. He was an ilegitimate child of Abraham and Hagar. And this is what was prophecised about Ishmael 4000 years ago, which is true even today
Genesis 16:11-12 11 The angel of the LORD also said to her: "You are now with child and you will have a son. You shall name him Ishmael, for the LORD has heard of your misery.
12 He will be a wild donkey of a man; his hand will be against everyone and everyone's hand against him, and he will live in hostility toward all his brothers."
Doesn't this charactierize Islam even to this day????
