وَجَزَاء سَيِّئَةٍ سَيِّئَةٌ مِّثْلُهَا فَمَنْ عَفَا وَأَصْلَحَ فَأَجْرُهُ عَلَى اللهِ إِنَّهُ لَا يُحِبُّ الظَّالِمِينَ وَلَمَنِ انتَصَرَ بَعْدَ ظُلْمِهِ فَأُوْلَئِكَ مَا عَلَيْهِم مِّن سَبِيلٍ إِنَّمَا السَّبِيلُ عَلَى الَّذِينَ يَظْلِمُونَ النَّاسَ وَيَبْغُونَ فِي الْأَرْضِ بِغَيْرِ الْحَقِّ أُوْلَئِكَ لَهُم عَذَابٌ أَلِيمٌ وَلَمَن صَبَرَ وَغَفَرَ إِنَّ ذَلِكَ لَمِنْ عَزْمِ الْأُمُورِ (42: 40-43)

And the revenge of an evil is an evil equal to it. Yet, he who forgave and reconciled his reward rests with God. Indeed, He does not like wrongdoers. And those who took revenge after they were oppressed, then there is no blame on them. The blame is only on them who oppress people and are rebellious in the land without justification. It is for these people for whom there is a grievous penalty. And indeed he who exercised restraint and forgave, then this is from among the matters of resolve. (42:40-43)
