Surah Al-Ma'idah, Verse 118

إِن تُعَذِّبۡهُمۡ فَإِنَّهُمۡ عِبَادُكَۖ وَإِن تَغۡفِرۡ لَهُمۡ فَإِنَّكَ أَنتَ ٱلۡعَزِيزُ ٱلۡحَكِيمُ١١٨

in tuʿadhib'hum fa-innahum ʿibāduka wa-in taghfir lahum fa-innaka anta l-ʿazīzu l-ḥakīmu

If You should punish them - indeed they are Your servants; but if You forgive them - indeed it is You who is the Exalted in Might, the Wise."
