It is narrated from Salim bin Abi J'ad, he says: Someone asked Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that a man kills a believer, but then repents, brings faith, does good deeds, and becomes guided. He said: Woe to you, from where will guidance come to such a killer? I heard your Prophet (peace and blessings be upon him) say: The murdered person will come clinging to his killer and will say: O my Lord! Ask him for what reason he killed me. By Allah! Allah Almighty revealed this verse to your Prophet and after revealing it, did not abrogate it. Woe to you, from where will such a killer get guidance?
