Arabic text
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
