Quran 3:65 — The Amramites (Ali-'Imran)
O followers of the scripture, why do you argue about Abraham, when the Torah and the Gospel were not revealed until after him? Do you not understand?
[3:64] Say, "O followers of the scripture, let us come to a logical agreement between us and you: that we shall not worship except GOD; that we never set up any idols besides Him, nor set up any human beings as lords beside GOD." If they turn away, say, "Bear witness that we are submitters."
[3:66] You have argued about things you knew; why do you argue about things you do not know? GOD knows, while you do not know.
