أَوْ تَقُولُوا۟ لَوْ أَنَّآ أُنزِلَ عَلَيْنَا ٱلْكِتَٰبُ لَكُنَّآ أَهْدَىٰ مِنْهُمْ ۚ فَقَدْ جَآءَكُم بَيِّنَةٌۭ مِّن رَّبِّكُمْ وَهُدًۭى وَرَحْمَةٌۭ ۚ فَمَنْ أَظْلَمُ مِمَّن كَذَّبَ بِـَٔايَٰتِ ٱللَّهِ وَصَدَفَ عَنْهَا ۗ سَنَجْزِى ٱلَّذِينَ يَصْدِفُونَ عَنْ ءَايَٰتِنَا سُوٓءَ ٱلْعَذَابِ بِمَا كَانُوا۟ يَصْدِفُونَ
Or lest ye should say: If the Scripture had been revealed unto us, we surely had been better guided than are they. Now hath there come unto you a clear proof from your Lord, a guidance and mercy; and who doeth greater wrong than he who denieth the revelations of Allah, and turneth away from them? We award unto those who turn away from Our revelations an evil doom because of their aversion.
Surah Al-An'aam(6:157)
