(Ahqaaf) 46 : 34
وَيَوْمَ يُعْرَضُ الَّذِينَ كَفَرُوا عَلَى النَّارِ أَلَيْسَ هَٰذَا بِالْحَقِّ ۖ قَالُوا بَلَىٰ وَرَبِّنَا ۚ قَالَ فَذُوقُوا الْعَذَابَ بِمَا كُنْتُمْ تَكْفُرُونَ
And on the Day the disbelievers will be presented upon the fire, ‘isn’t this the Truth’; they will say: Yes, by our Lord! Then you taste the punishment for what you had been disbelieving.
