In the Name of Allah, The Most Merciful, The Most Gracious
Narrated by Said bin Jubair:
‘AbdurRahman bin Abza said, “Ask Ibn ‘Abbas about these two Qur’anic Verses: ‘Nor kill such life as Allah has made sacred, Except for just cause.’ (25.168) “And whoever kills a believer intentionally, his recompense is Hell. (4.93) So I asked Ibn ‘Abbas who said, “When the Verse that is in Sura-al-Furqan was revealed, the pagans of Mecca said, ‘But we have slain such life as Allah has made sacred, and we have invoked other gods along with Allah, and we have also committed fornication’ So Allah revealed: — ‘Except those who repent, believe, and do good– (25.70)
So this Verse was concerned with those people. As for the Verse in Surat-an-Nisa (4-93), it means that if a man, after understanding Islam and its laws and obligations, murders somebody, then his punishment is to dwell in the (Hell) Fire forever.” Then I mentioned this to Mujahid who said, “Except the one who regrets (one’s crime).” –Shahi Bukhari Vo. 5, No. 194.
What Our Lord Allah (Sob) Says in The Holy Qur’an:
But whoever kills a believer intentionally – his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment you who have believed, when you go forth [to fight] in the cause of Allah, investigate; and do not say to one who gives you [a greeting of] peace “You are not a believer,” aspiring for the goods of worldly life; for with Allah are many acquisitions. You [yourselves] were like that before; then Allah conferred His favor upon you, so investigate. Indeed Allah is ever, with what you do, acquainted. – Holy Qur’an 4:93-94.
And those who do not invoke with Allah another deity or kill the soul which Allah has forbidden [to be killed], except by right, and do not commit unlawful sexual intercourse. And whoever should do that will meet a penalty. Multiplied for him is the punishment on the Day of Resurrection, and he will abide therein humiliated – Except for those who repent, believe and do righteous work. For them Allah will replace their evil deeds with good. And ever is Allah Forgiving and Merciful. Holy Qur’an 25:68-70.
