Surah Al-Ahqaf 46:34

وَيَوْمَ يُعْرَضُ ٱلَّذِينَ كَفَرُوا۟ عَلَى ٱلنَّارِ أَلَيْسَ هَـٰذَا بِٱلْحَقِّ ۖ قَالُوا۟ بَلَىٰ وَرَبِّنَا ۚ قَالَ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ

And the Day those who disbelieved are exposed to the Fire [it will be said], "Is this not the truth?" They will say, "Yes, by our Lord." He will say, "Then taste the punishment for what you used to deny."

Translation: Saheeh International
