Abraham
Do you claim that Abraham, Ishmael, Isaac, Jacob, and their descendants were Jews or Christians? Say, 'Do you know better, or does Allah?' Who is more unjust than one who conceals a testimony from Allah? Allah is never unaware of what you do.
2:140Or say ye that Abraham, and Ishmael, and Isaac, and Jacob, and the tribes were Jews or Christians? Say: Do ye know best, or doth Allah? And who is more unjust than he who hideth a testimony which he hath received from Allah? Allah is not unaware of what ye do.
