Surah Al-An'am (The Cattle), Verse 30

وَلَوْ تَرٰۤی اِذْ وُقِفُوْا عَلٰی رَبِّهِمْ قَالَ اَلَیْسَ هٰذَا بِالْحَقِّ قَالُوْا بَلٰی وَرَبِّنَا قَالَ فَذُوْقُوا الْعَذَابَ بِمَا كُنْتُمْ تَكْفُرُوْنَ 

Wa law taraa iz wuqifoo 'alaa Rabbihim; qaala alaisa haazaa bilhaqq; qaaloo balaa wa Rabbinaa; qaala fazooqul 'azaaba bimaa kuntum takfuroon

“If thou couldst but see when they are confronted with their Lord! He will say: "Is not this the truth?" They will say: "Yea, by our Lord!" He will say: "Taste ye then the penalty, because ye rejected Faith."”
