Al-Hajj 60

ذَٰلِكَ وَمَنْ عَاقَبَ بِمِثْلِ مَا عُوقِبَ بِهِۦ ثُمَّ بُغِىَ عَلَيْهِ لَيَنصُرَنَّهُ ٱللَّهُ إِنَّ ٱللَّهَ لَعَفُوٌّ غَفُورٌ ﴿٦٠﴾

Thalika waman AAaqaba bimithli ma AAooqiba bihi thumma bughiya AAalayhi layansurannahu Allahu inna Allaha laAAafuwwun ghafoorun

That is so. And whoever has retaliated with the like of that which he was made to suffer, and then has again been wronged, Allah will surely help him. Verily! Allah indeed is Oft-Pardoning, Oft-Forgiving. The Noble Quran
