وَإِذَا تُتْلَىٰ عَلَيْهِ ءَايَٰتُنَا وَلَّىٰ مُسْتَكْبِرًۭا كَأَن لَّمْ يَسْمَعْهَا كَأَنَّ فِىٓ أُذُنَيْهِ وَقْرًۭا ۖ فَبَشِّرْهُ بِعَذَابٍ أَلِيمٍ
And when Our revelations are recited unto him he turneth away in pride as if he heard them not, as if there were a deafness in his ears. So give him tidings of a painful doom.
