وَيَوْمَ يُعْرَضُ ٱلَّذِينَ كَفَرُوا۟ عَلَى ٱلنَّارِ أَلَيْسَ هَٰذَا بِٱلْحَقِّ ۖ قَالُوا۟ بَلَىٰ وَرَبِّنَا ۚ قَالَ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ
And on the day when those who disbelieve are exposed to the Fire (they will be asked): Is not this real? They will say: Yea, by our Lord. He will say: Then taste the doom for that ye disbelieved.
