صحيح البخاري

Narrated Sa`id 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.'

Then I mentioned this to Mujahid who said, "Except the one who regrets (one's crime) . "
