Al-Baqarah 2:140

أَمۡ تَقُولُونَ إِنَّ إِبۡرَٰهِـۧمَ وَإِسۡمَٰعِيلَ وَإِسۡحَٰقَ وَيَعۡقُوبَ وَٱلۡأَسۡبَاطَ كَانُواْ هُودًا أَوۡ نَصَٰرَىٰۗ قُلۡ ءَأَنتُمۡ أَعۡلَمُ أَمِ ٱللَّهُۗ وَمَنۡ أَظۡلَمُ مِمَّن كَتَمَ شَهَٰدَةً عِندَهُۥ مِنَ ٱللَّهِۗ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعۡمَلُونَ 140

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 Allah?" And who is more unjust than one who conceals a testimony he has from Allah? And Allah is not unaware of what you do
