Sura al-Baqara 2:140

أَمْ تَقُولُونَ إِنَّ إِبْرَٰهِـۧمَ وَإِسْمَٰعِيلَ وَإِسْحَٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطَ كَانُوا۟ هُودًا أَوْ نَصَٰرَىٰ قُلْ ءَأَنتُمْ أَعْلَمُ أَمِ ٱللَّـهُ وَمَنْ أَظْلَمُ مِمَّن كَتَمَ شَهَٰدَةً عِندَهُۥ مِنَ ٱللَّـهِ وَمَا ٱللَّـهُ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ

am taqūlūna inna ibrāhīma wa-ismāʿīla wa-isḥāqa wa-yaʿqūba wa-l-asbāṭa kānū hūdan aw naṣārā qul aʾantum aʿlamu ami allāhu wa-man aẓlamu mimman katama shahādatan ʿindahu mina allāhi wa-mā allāhu bi-ghāfilin ʿammā taʿmalūna

Or do ye say that Abraham, Isma'il Isaac, Jacob and the Tribes were Jews or Christians? Say: Do ye know better than Allah? Ah! who is more unjust than those who conceal the testimony they have from Allah? but Allah is not unmindful of what ye do!
