Surah Al-Isra Verse 33 - English Translation by Muhammad Asad
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 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]
