وَلَوْ تَرَىٰٓ إِذْ وُقِفُوا۟ عَلَىٰ رَبِّهِمْ ۚ قَالَ أَلَيْسَ هَٰذَا بِٱلْحَقِّ ۚ قَالُوا۟ بَلَىٰ وَرَبِّنَا ۚ قَالَ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ
If thou couldst see when they are set before their Lord! He will say: Is not this real? They will say: Yea, verily, by our Lord! He will say: Taste now the retribution for that ye used to disbelieve.
