Sahih al-Bukhari Book 65, Hadith 288
`Abdur-Rahman bin Abza ordered me to ask Ibn `Abbas regarding the two Verses (the first of which
was ):
"And whosoever murders a believer intentionally." (4.93) So I asked him, and he said, "Nothing has
abrogated this Verse." About (the other Verse): 'And those who invoke not with Allah any other god.'
he said, "It was revealed concerning the pagans."
Ibn Abza said to me, "Ask Ibn `Abbas regarding the Statement of Allah: 'And whoever murders a believer intentionally, his recompense is Hell.' (4.69) And also His Statement: '...nor kill such life as Allah has forbidden, except for a just cause .....except those who repent, believe, and do good deeds.' " (25.68-70) So I asked Ibn `Abbas and he said, "When this (25.68-69) was revealed, the people of Mecca said, "We have invoked other gods with Allah, and we have murdered such lives which Allah has made sacred, and we have committed illegal sexual intercourse. So Allah revealed: 'Except those who repent, believe, and do good deeds and Allah is Oft-Forgiving, Most Merciful.' (25.70)
Five (great events) have passed: the Smoke, the Moon, the Romans, the Mighty grasp and the constant Punishment which occurs in 'So the torment will be yours forever.' (25.77)
