Surah Al-Baqarah Ayah 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 ١٤٠

Am taqūlūna inna ibrāhīma wa ismāʿīla wa isḥāqa wa yaʿqūba wal-asbāṭa kānū hūdan aw naṣārā, qul aʾantum aʿlamu amillāh, wa man aẓlamu mimman katama shahādatan ʿindahū minallāh, wa mallāhu bighāfilin ʿammā taʿmalūn.

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 testimony¹ he has from Allāh? And Allāh is not unaware of what you do.
