Abraham (novanet)
Distinguish between Arabs and Muslims. Abraham (or Ibrahim) is indeed the legendary ancestor of the Arabs, through his illegitimate son Ishmael, as he is the ancestor of the Jews through his legitimate son Issac. As Ishamael was the older, the Arabs/Muslims tend to gloss the illegitimacy and insist that Ishmael, not Isaac, was the one all the stories are about (e.g., was the one NOT sacrificed to prove Abraham's devotion). In fairness, Ishmael wasn't "illegitimate" in the same sense that Europeans would think of it; although Abraham wasn't married to Ishmael's mother, Hagar, he was entitled to have children with her as she was his wife's "handmaiden" or slave.
