Al-Ma'idah 5:118

إِن تُعَذِّبْهُمْ فَإِنَّهُمْ عِبَادُكَ ۖ وَإِن تَغْفِرْ لَهُمْ فَإِنَّكَ أَنتَ ٱلْعَزِيزُ ٱلْحَكِيمُ

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."
