Or do ye say that Abraham, Isma’il Isaac, Jacob and the Tribes were Jews or Christians? Say: Do ye know better than Allah? Ah! who is more unjust than those who conceal the testimony they have from Allah? but Allah is not unmindful of what ye do!
“(and not strict monotheists) i.e. is your position, O Jews and Christians! that the prophets of old and the patriarchs belonged to the Jewish or Christian cults in contradiction to the true monotheism of Islam?” (p. 90)
