Al-Baqara 2:140

Or do you say that Abraham, Ishmael, Isaac, Jacob, and the descendants [of Jacob] were Jews or Christians?” Say, “Are you more knowledgeable or Allah?” Who does greater wrong than the one who hides a testimony he has from Allah? But Allah is not unaware of what you do.

Or do you say that Abraham and Ishmael and Isaac and Jacob and the Descendants were Jews or Christians? Say, "Are you more knowing or is Allāh?" And who is more unjust than one who conceals a testimony[49] he has from Allāh? And Allāh is not unaware of what you do.

[49] Statements in previous scriptures attesting to the nature of Allāh's religion (Islām) and the coming of Prophet Muḥammad (ﷺ) .

140. Or say you that Ibrâhîm (Abraham), Ismâ‘îl (Ishmael), Ishâq (Isaac), Ya‘qûb (Jacob) and Al-Asbât [the offspring of the twelve sons of Ya‘qûb (Jacob)] were Jews or Christians? Say, "Do you know better or does Allâh (knows better ... that they all were Muslims)? And who is more unjust than he who conceals the testimony [i.e. to believe in Prophet Muhammad صلى الله عليه وسلم when he comes, as is written in their Books. (See Verse 7:157)] he has from Allâh? And Allâh is not unaware of what you do."

Or 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.
