question #3 Sahih al-Bukhari 4762, Book 65, Hadith 284 : What role does the historical context of revelation play in understanding the Quranic verses about murder?

That he asked Sa`id bin Jubair, “Is there any repentance of the one who has murdered a believer
intentionally?” Then I recited to him:–
“Nor kill such life as Allah has forbidden except for a just cause.” Sa`id said, “I recited this very Verse
before Ibn `Abbas as you have recited it before me. Ibn `Abbas said, ‘This Verse was revealed in
Mecca and it has been abrogated by a Verse in Surat-An-Nisa which was later revealed in Medina.”
