Don’t blame God’s Law for Islam. They made up their own.
As did the king james version of the bible.The God of Abraham is the same for christians, jews and muslims.Hagar, the mother of Ishmael, was an Arab slave.Ishmael was a half brother to Isaac. Ishmael and mother was sent packing after Sarah got jealous and told Abraham they had to go.This is where the split comes between muslims and christians.
