﴿ إِن تُعَذِّبْهُمْ فَإِنَّهُمْ عِبَادُكَ ۖ وَإِن تَغْفِرْ لَهُمْ فَإِنَّكَ أَنتَ ٱلْعَزِيزُ ٱلْحَكِيمُ ﴾

“If thou cause them to suffer - verily, they are Thy servants; and if Thou forgive them - verily, Thou alone art almighty, truly wise!"”

(If Thou punish them, lo! they are Thy slaves, and if Thou forgive them (lo! they are Your slaves). Lo! Thou, only Thou art the Mighty, the Wise). This verse has already been explained.
