وَلَا تَقْتُلُوا۟ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ ۗ وَمَن قُتِلَ مَظْلُومًا فَقَدْ جَعَلْنَا لِوَلِيِّهِۦ سُلْطَـٰنًا فَلَا يُسْرِف فِّى ٱلْقَتْلِ ۖ إِنَّهُۥ كَانَ مَنصُورًا

And do not kill the soul [i.e., person] which Allāh 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].
— Saheeh International
Do not take life, which God has made sacred, except by right: if anyone is killed wrongfully, We have given authority to the defender of his rights, but he should not be excessive in taking life, for he is already aided [by God].
— M. A. S. Abdel Haleem
And do not kill anyone whose killing Allâh has forbidden, except for a just cause. And whoever is killed wrongfully (Mazlûman intentionally with hostility and oppression and not by mistake), We have given his heir the authority [to demand Qisâs, - Law of Equality in punishment - or to forgive, or to take Diyah (blood money)]. But let him not exceed limits in the matter of taking life (i.e he should not kill except the killer). Verily, he is helped (by the Islâmic law).
