أَو تَقولوا لَو أَنّا أُنزِلَ عَلَينَا الكِتابُ لَكُنّا أَهدىٰ مِنهُم ۚ فَقَد جاءَكُم بَيِّنَةٌ مِن رَبِّكُم وَهُدًى وَرَحمَةٌ ۚ فَمَن أَظلَمُ مِمَّن كَذَّبَ بِآياتِ اللَّهِ وَصَدَفَ عَنها ۗ سَنَجزِي الَّذينَ يَصدِفونَ عَن آياتِنا سوءَ العَذابِ بِما كانوا يَصدِفونَ

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 Allah 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.
