﴿ وَلَا تَقْتُلُوا۟ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ ۗ وَمَن قُتِلَ مَظْلُومًۭا فَقَدْ جَعَلْنَا لِوَلِيِّهِۦ سُلْطَٰنًۭا فَلَا يُسْرِف فِّى ٱلْقَتْلِ ۖ إِنَّهُۥ كَانَ مَنصُورًۭا ﴾

“And do not take any human being's life -[the life] which God has willed to be, sacred-otherwise than in [the pursuit of] justice. Hence, if anyone has been slain wrongfully, We have empowered the defender of his rights [to exact a just retribution]; but even so, let him not exceed the bounds of equity in [retributive] killing. [And as for him who has been slain wrongfully -] behold, he is indeed succoured [by God]!”

And do not slay the soul whose life God has made inviolable except with due cause. Whoever is slain wrongfully We have certainly given his heir the one inheriting from him a warrant a sanction to retaliate against the slayer; but let him not commit excess let him not overstep the bounds in slaying by slaying other than the killer of the one slain or by other than that instrument with which he the slain was killed; for he is supported by the Law.
