Sura al-Anʿām 6:157

أَوْ تَقُولُوا۟ لَوْ أَنَّآ أُنزِلَ عَلَيْنَا ٱلْكِتَٰبُ لَكُنَّآ أَهْدَىٰ مِنْهُمْ فَقَدْ جَآءَكُم بَيِّنَةٌ مِّن رَّبِّكُمْ وَهُدًى وَرَحْمَةٌ فَمَنْ أَظْلَمُ مِمَّن كَذَّبَ بِـَٔايَٰتِ ٱللَّـهِ وَصَدَفَ عَنْهَا سَنَجْزِى ٱلَّذِينَ يَصْدِفُونَ عَنْ ءَايَٰتِنَا سُوٓءَ ٱلْعَذَابِ بِمَا كَانُوا۟ يَصْدِفُونَ

aw taqūlū law annā unzila ʿalaynā l-kitābu la-kunnā ahdā minhum fa-qad jāʾakum bayyinatun min rabbikum wa-hudan wa-raḥmatun fa-man aẓlamu mimman kadhdhaba bi-āyāti allāhi wa-ṣadafa ʿanhā sanajzī lladhīna yaṣdifūna ʿan āyātinā suʾa l-ʿadhābi bi-mā kānū yaṣdifūna

Or lest ye should say: "If the Book had only been sent down to us, we should have followed its guidance better than they." Now then hath come unto you a clear (sign) from your Lord,- and a guide and a mercy: then who could do more wrong than one who rejecteth Allah's signs, and turneth away therefrom? In good time shall We requite those who turn away from Our signs, with a dreadful penalty, for their turning away.
