It is narrated from Khaythamah that Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) was sitting among a group of people, and they (some people) mentioned Sayyiduna Ali (may Allah be pleased with him) and reviled him. Sayyiduna Sa'd said: "Hold your tongues concerning the Companions of the Messenger of Allah (peace and blessings be upon him), for we committed a sin in the time of the Messenger of Allah (peace and blessings be upon him) (taking ransom for the captives), upon which Allah, the Mighty and Majestic, revealed this verse: 'Were it not for a decree from Allah that had preceded, a great punishment would have touched you for what you took' [Surah al-Anfal: 68] . So I hope that a mercy from Allah had already been written for us." One of them said: "By Allah, he used to hate you and call you 'al-Akhnas'." At this Sa'd laughed so much that laughter overcame him. Then he said: "Does it not happen that a man becomes angry with his brother over some matter that occurs between them, yet that does not affect his (the brother's) trustworthiness and integrity?" And he said another word as well. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and they did not record it.
