وَلا تَقتُلُوا النَّفسَ الَّتي حَرَّمَ اللَّهُ إِلّا بِالحَقِّ ۗ وَمَن قُتِلَ مَظلومًا فَقَد جَعَلنا لِوَلِيِّهِ سُلطانًا فَلا يُسرِف فِي القَتلِ ۖ إِنَّهُ كانَ مَنصورًا

And do not kill the soul which Allah 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].
