The Quran is sharply contrasted to the Bible when it comes to the status and treatment of infidels (i.e. non-believers) and other races (in particular Jews).
Ishmael’s mother, Hagar, was told by an angel that he would live in conflict with his brothers. (Gen 16:11-12) Not only was this prophecy true of Ishmael, but even his descendants “lived in hostility toward all their brothers.” (Gen 25:18)
Today Ishmael’s descendants (the Arab races) still live in hostility, both amongst themselves (Sunni and Shiite) and with their brother race – the Jews (Isaac’s descendants).
