It is narrated from Sayyiduna Abdullah bin al-Harith bin Nawfal (may Allah be pleased with him) that he related: I was returning from Siffin with Sayyiduna Mu'awiyah (may Allah be pleased with him). Sayyiduna Mu'awiyah and Abu al-A'war al-Sulami were riding on one side, while Sayyiduna Amr bin al-As and his son (Abdullah) were riding on the other side. I was right between them, and there was no one there besides me; sometimes I would speed up my mount and draw near to these, and sometimes I would reach those. I heard Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) say to his father: "O my father! Did you not hear the Messenger of Allah (peace and blessings be upon him) say to Sayyiduna Ammar (may Allah be pleased with him) when he was building the mosque: 'You are indeed very eager for reward'?" He said: "Yes (may Allah be pleased with him)." And he (peace and blessings be upon him) had (further) said: "You are certainly among the people of Paradise, and a rebellious group will kill you." He replied: "Yes, I heard this saying." Abdullah asked: "Then why did you people kill him?" The narrator says: At this he (Sayyiduna Amr bin al-As) turned to Sayyiduna Mu'awiyah (may Allah be pleased with him) and said: "O Abu Abd al-Rahman! Do you hear what this one (my son) is saying?" So he repeated that statement. Sayyiduna Mu'awiyah (may Allah be pleased with him) said: "Woe to you! You keep stumbling in your speech. Did we kill him? He was only killed by those who brought him (with them to the war)."
The chain of this hadith is sahih (authentic), and Imam Ahmad bin Hanbal recorded it in his Musnad (6929).
