Surah Al-Israوَلَا تَقۡتُلُواْ ٱلنَّفۡسَ ٱلَّتِي حَرَّمَ ٱللَّهُ إِلَّا بِٱلۡحَقِّۗ وَمَن قُتِلَ مَظۡلُومٗا فَقَدۡ جَعَلۡنَا لِوَلِيِّهِۦ سُلۡطَٰنٗا فَلَا يُسۡرِف فِّي ٱلۡقَتۡلِۖ إِنَّهُۥ كَانَ مَنصُورٗا
And do not kill any person, whose (killing) God has made unlawful except (when his killing is) for the right (cause). And whoever is killed unjustly, then We have given authority to his heir, so let his (heir) not exceed the limits in killing (because) he is helped (by the law)
