Surah Al-Isra Verse 33 - English Translation by Safi Kaskas
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 the soul which God has forbidden-unless in the pursuit of justice. If anyone has been killed unjustly, We have given legal recourse to his heir [to claim justice]; but, even then, he should not be excessive in taking life. For he is helped [by God's law]
