﴿ وَجَزَٰٓؤُا۟ سَيِّئَةٍۢ سَيِّئَةٌۭ مِّثْلُهَا ۖ فَمَنْ عَفَا وَأَصْلَحَ فَأَجْرُهُۥ عَلَى ٱللَّهِ ۚ إِنَّهُۥ لَا يُحِبُّ ٱلظَّٰلِمِينَ ﴾

“But [remember that an attempt at] requiting evil may, too, become an evil: hence, whoever par­dons [his foe] and makes peace, his reward rests with God - for, verily, He does not love evildoers.”
