Quran 2:140 Al-Baqarah, ayah 140 of 286

أَمْ تَقُولُونَ إِنَّ إِبْرَٰهِـۧمَ وَإِسْمَـٰعِيلَ وَإِسْحَـٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطَ كَانُوا۟ هُودًا أَوْ نَصَـٰرَىٰ ۗ قُلْ ءَأَنتُمْ أَعْلَمُ أَمِ ٱللَّهُ ۗ وَمَنْ أَظْلَمُ مِمَّن كَتَمَ شَهَـٰدَةً عِندَهُۥ مِنَ ٱللَّهِ ۗ وَمَا ٱللَّهُ بِغَـٰفِلٍ عَمَّا تَعْمَلُونَ ۝١٤٠

2:140 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.
