أَمْ تَقُولُونَ إِنَّ إِبْرَٰهِۦمَ وَإِسْمَٰعِيلَ وَإِسْحَٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطَ كَانُوا۟ هُودًا أَوْ نَصَٰرَىٰ ۗ قُلْ ءَأَنتُمْ أَعْلَمُ أَمِ ٱللَّهُ ۗ وَمَنْ أَظْلَمُ مِمَّن كَتَمَ شَهَٰدَةً عِندَهُۥ مِنَ ٱللَّهِ ۗ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ
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.
