Justice and Retaliation (Qisas)

وَلَا تَقْتُلُوا۟ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ ۗ وَمَن قُتِلَ مَظْلُومًا فَقَدْ جَعَلْنَا لِوَلِيِّهِۦ سُلْطَـٰنًا فَلَا يُسْرِف فِّى ٱلْقَتْلِ ۖ إِنَّهُۥ كَانَ مَنصُورًا

And do not kill the soul [i.e., person] which Allāh has forbidden, except by right. And whoever is killed unjustly - We have given his heir authority, but let him not exceed limits in [the matter of] taking life. Indeed, he has been supported [by the law].

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

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.
