Jubayr bin Nufayr (may Allah have mercy on him) narrates: After the martyrdom of Sayyiduna Uthman (may Allah be pleased with him), we were encamped with the army of Sayyiduna Mu'awiyah (may Allah be pleased with him), when Sayyiduna Murrah bin Ka'b al-Bahzi (may Allah be pleased with him) stood up and said: Listen, by Allah! Were it not for something I heard from the Messenger of Allah (peace and blessings be upon him), I would not have stood in this place. When Sayyiduna Mu'awiyah (may Allah be pleased with him) heard mention of the Messenger of Allah (peace and blessings be upon him), he made the people sit down. Then Sayyiduna Murrah (may Allah be pleased with him) said: We were sitting with the Messenger of Allah (peace and blessings be upon him) when Sayyiduna Uthman (may Allah be pleased with him) passed by, his hair combed and well dressed, and the Messenger of Allah (peace and blessings be upon him) said: "A trial will soon emerge from beneath my feet - or from beneath my foot - and this man and his followers will be upon guidance on that day." I stood up, took hold of Sayyiduna Uthman's shoulder and turned him towards the Messenger of Allah (peace and blessings be upon him), and I said: Is it this one? He (peace and blessings be upon him) said: "Yes, this man and his followers will be upon guidance on that day." At that, Sayyiduna Abdullah bin Hawalah al-Ansari (may Allah be pleased with him) stood up from near the pulpit and said: Are you speaking about this one? He said: Yes. Abdullah bin Hawalah said: "Listen, by Allah! I was present in that gathering, and had I known that there was someone in the army who would confirm me, I would have been the first to tell the people of it."
