33rd Ayah from Surah Al Isra
Sahih International
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].
Abdul Haleem
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].
Mohsin Khan/Hilali
And do not kill anyone which Allah has forbidden, except for a just cause. And whoever is killed (intentionally with hostility and oppression and not by mistake), We have given his heir the authority [(to demand Qisas, Law of Equality in punishment or to forgive, or to take Diya (blood money)]. But let him not exceed limits in the matter of taking life (i.e. he should not kill except the killer only). Verily, he is helped (by the Islamic law).
Taqi Usmani
Do not kill any person the life of whom is sanctified by Allah, except for a just reason. And whoever is killed unjustly, We have invested his heir with authority (of equal retaliation), but he must not cross the limit in the matter of killing. Surely, he will be helped.
Pickthall
And slay not the life which Allah hath forbidden save with right. Whoso is slain wrongfully, We have given power unto his heir, but let him not commit excess in slaying. Lo! he will be helped.
Pickthall
Nor take life - which Allah has made sacred - except for just cause. And if anyone is slain wrongfully, we have given his heir authority (to demand qisas or to forgive): but let him not exceed bounds in the matter of taking life; for he is helped (by the Law).
