Sayyiduna Amr bin al-'As (may Allah be pleased with him) narrates: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever repents before his death, even by the interval between two milkings of a she-camel (that is, just a little while before), Allah Almighty accepts his repentance."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Khalid except Abd al-Salam; Abd al-Mu'min is alone in narrating it; and this hadith is narrated from Sayyiduna Amr bin al-'As (may Allah be pleased with him) only with this chain."
