قُلْ أَرَءَيْتُمْ إِن كَانَ مِنْ عِندِ ٱللَّهِ وَكَفَرْتُم بِهِۦ وَشَهِدَ شَاهِدٌۭ مِّنۢ بَنِىٓ إِسْرَٰٓءِيلَ عَلَىٰ مِثْلِهِۦ فَـَٔامَنَ وَٱسْتَكْبَرْتُمْ ۖ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ
Bethink you: If it is from Allah and ye disbelieve therein, and a witness of the Children of Israel hath already testified to the like thereof and hath believed, and ye are too proud (what plight is yours)? Lo! Allah guideth not wrong-doing folk.
