It is narrated from Amir bin Sa'd that Sayyiduna Mu'awiyah (may Allah be pleased with him) said to Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him): "What prevents you from reviling Ibn Abi Talib (Sayyiduna Ali, may Allah be pleased with him)?" He replied: "As long as I remember the three things that the Messenger of Allah (peace and blessings be upon him) said in his favour, I will never revile him; any single one of those (virtues) would be dearer to me than a wealth of red camels." Sayyiduna Mu'awiyah (may Allah be pleased with him) asked: "O Abu Ishaq! What are they?" He said: "I will not speak ill of him as long as I remember the time when revelation came down and he (peace and blessings be upon him) covered Sayyiduna Ali, his two sons and Sayyidah Fatimah (may Allah be pleased with them) beneath his cloak, and then supplicated: 'Rabbi inna ha'ula'i ahlu bayti' (O my Lord! These are my family, my Ahl al-Bayt). Likewise, I will not speak ill of him as long as I remember the occasion of the expedition of Tabuk, when the Messenger of Allah (peace and blessings be upon him) left him behind (in Madinah), and Sayyiduna Ali (may Allah be pleased with him) said: (O Messenger of Allah!) Have you left me behind with the children and the women? He (peace and blessings be upon him) said: 'Are you not pleased that your position with me is the same as that of Harun (peace be upon him) with Musa (peace be upon him), except that there is no prophethood after me?' And I will not speak ill of him as long as I remember the day of Khaybar, when the Messenger of Allah (peace and blessings be upon him) said: 'I will give this banner to a man who loves Allah and His Messenger, and Allah will grant victory at his hands.' So all of us began hoping for the attention of the Messenger of Allah (peace and blessings be upon him). Then he (peace and blessings be upon him) asked: 'Where is Ali?' The Companions said: His eyes are sore (he has an eye inflammation). He (peace and blessings be upon him) said: 'Call him.' When he was called, he (peace and blessings be upon him) applied his blessed saliva to his eyes and handed him the banner, and then Allah granted victory at his hands." The narrator says: So, by Allah! Sayyiduna Mu'awiyah (may Allah be pleased with him) did not say a single word about him until he departed from Madinah. This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but they did not record it with this wording (sequence of words), while the two Shaykhs agreed on recording the hadith of brotherhood (al-Mu'akhat) and the hadith of the banner.
