Al-An'am 157

أَوْ تَقُولُوا۟ لَوْ أَنَّآ أُنزِلَ عَلَيْنَا ٱلْكِتَـٰبُ لَكُنَّآ أَهْدَىٰ مِنْهُمْ ۚ فَقَدْ جَآءَكُم بَيِّنَةٌ مِّن رَّبِّكُمْ وَهُدًى وَرَحْمَةٌ ۚ فَمَنْ أَظْلَمُ مِمَّن كَذَّبَ بِـَٔايَـٰتِ ٱللَّهِ وَصَدَفَ عَنْهَا ۗ سَنَجْزِى ٱلَّذِينَ يَصْدِفُونَ عَنْ ءَايَـٰتِنَا سُوٓءَ ٱلْعَذَابِ بِمَا كَانُوا۟ يَصْدِفُونَ

aw taqūlū law annā unzila ʿalaynā l-kitābu lakunnā ahdā min'hum faqad jāakum bayyinatun min rabbikum wahudan waraḥmatun faman aẓlamu mimman kadhaba biāyāti l-lahi waṣadafa ʿanhā sanajzī alladhīna yaṣdifūna ʿan āyātinā sūa l-ʿadhābi bimā kānū yaṣdifūna

Or lest you say, "If only the Scripture had been revealed to us, we would have been better guided than they." So there has [now] come to you a clear evidence from your Lord and a guidance and mercy. Then who is more unjust than one who denies the verses of Allāh and turns away from them? We will recompense those who turn away from Our verses with the worst of punishment for their having turned away.
