Quran 3:66 — The Amramites (Ali-'Imran)

You have argued about things you knew; why do you argue about things you do not know? GOD knows, while you do not know.

[3:65] 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?

[3:67] Abraham was neither Jewish, nor Christian; he was a monotheist submitter. He never was an idol worshiper.
