Quran Al-Hajj 22:60
ذَٰلِكَۖ وَمَنۡ عَاقَبَ بِمِثۡلِ مَا عُوقِبَ بِهِۦ ثُمَّ بُغِيَ عَلَيۡهِ لَيَنصُرَنَّهُ ٱللَّهُۚ إِنَّ ٱللَّهَ لَعَفُوٌّ غَفُورٞ
Translation
That [is so]. And whoever responds [to injustice] with the equivalent of that with which he was harmed and then is tyrannized - Allāh will surely aid him. Indeed, Allāh is Pardoning and Forgiving.
