أَوۡ تَقُولُواْ لَوۡ أَنَّآ أُنزِلَ عَلَيۡنَا ٱلۡكِتَٰبُ لَكُنَّآ أَهۡدَىٰ مِنۡهُمۡۚ فَقَدۡ جَآءَكُم بَيِّنَةٞ مِّن رَّبِّكُمۡ وَهُدٗى وَرَحۡمَةٞۚ فَمَنۡ أَظۡلَمُ مِمَّن كَذَّبَ بِـَٔايَٰتِ ٱللَّهِ وَصَدَفَ عَنۡهَاۗ سَنَجۡزِي ٱلَّذِينَ يَصۡدِفُونَ عَنۡ ءَايَٰتِنَا سُوٓءَ ٱلۡعَذَابِ بِمَا كَانُواْ يَصۡدِفُونَ

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.
