Quran 18:87 from Surah Al-Kahf on Divine Marvels.
قَالَ أَمَّا مَن ظَلَمَ فَسَوۡفَ نُعَذِّبُهُۥ ثُمَّ يُرَدُّ إِلَىٰ رَبِّهِۦ فَيُعَذِّبُهُۥ عَذَابٗا نُّكۡرٗا
English translation: He said As for (one) who wrongs then soon we will punish him Then he will be returned to his Lord and He will punish him (with) a punishment terrible
Transliteration: qala amma man zalama fasawfa nu'adhibuhu thumma yuraddu ila rabbihi fayu'adhibuhu adhaban nuk'ran
