وَلَا تَقۡتُلُواْ ٱلنَّفۡسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلۡحَقِّ ۗ وَمَن قُتِلَ مَظۡلُومًا فَقَدۡ جَعَلۡنَا لِوَلِيِّهِۦ سُلۡطَٰنًا فَلَا يُسۡرِف فِّى ٱلۡقَتۡلِ ۖ إِنَّهُۥ كَانَ مَنصُورًا
Nor take life - which Allah has made sacred - except for just cause. And if anyone is slain wrongfully, we have given his heir authority (to demand qisas or to forgive): but let him not exceed bounds in the matter of taking life; for he is helped (by the Law).<br/>
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].
