{ And do not kill the soul that Allah has forbidden, except with just cause; whoever is killed wrongly, we have given authority to his heir; but let one not go to extremes in killing, for indeed he will be aided } Al-israa 33

Al-Dahhak (may Allah be pleased with him), regarding His word { And do not kill the soul that Allah has forbidden, except with just cause } and the rest of the verse, said: This was in Mecca when the Prophet (SAW) was there, and was the first thing in the Qur’an to come down in regards to killing. The Idolaters [Mushrikun] in Mecca were murdering the Prophet’s (SAW) Companions and He said: Whoever of the Idolaters kills one of you all, do not let his killing you make you kill his father or brother or any other of his relatives, even if they are Idolaters – do not kill anyone except the one who kills one of you. But this was before the “Absolution” [Surah Al-tawba] came down, and before they were ordered to kill the Idolaters.
