If You should punish them - indeed they are Your servants; but (5:118)

﴿إِن تُعَذِّبْهُمْ فَإِنَّهُمْ عِبَادُكَ ۖ وَإِن تَغْفِرْ لَهُمْ فَإِنَّكَ أَنتَ الْعَزِيزُ الْحَكِيمُ﴾
[ المائدة: 118]

5:118 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.

If you punish them, O Lord, they are your servants and You can do with them as You wish.
If You graciously forgive those of them who had faith, nothing can stop You from doing so because You are the Mighty, Who cannot be overpowered, and the Wise in Your handling of matters.

"If You punish them, they are Your slaves, and if You forgive them, verily You, only You are the All-Mighty, the All-Wise."
