Surah Al-Ahqaf (The Sand-Hills), Verse 34

وَیَوْمَ یُعْرَضُ الَّذِیْنَ كَفَرُوْا عَلَی النَّارِ اَلَیْسَ هٰذَا بِالْحَقِّ قَالُوْا بَلٰی وَرَبِّنَا قَالَ فَذُوْقُوا الْعَذَابَ بِمَا كُنْتُمْ تَكْفُرُوْنَ ۟

Wa Yawma yu'radul lazeena kafaroo 'alan naari alaisa haaza bil haqq; qaaloo balaa wa Rabbinaa; qaala fazooqul 'azaaba bimaa kuntum takfuroon

“And on the Day that the Unbelievers will be placed before the Fire, (they will be asked,) "Is this not the Truth?" they will say, "Yea, by Our Lord!" (One will say:) "Then taste ye the Penalty, for that ye were wont to deny (Truth)!"”
