It is narrated from Hanzala bin Khuwailid Anbari, he says: I was present with Sayyiduna Muawiyah (may Allah be pleased with him) when two men came to him and started arguing about the head of Sayyiduna Ammar (may Allah be pleased with him), each claiming that he had killed him. Upon hearing their words, Sayyiduna Abdullah bin Amr (may Allah be pleased with him) said: Each of you may take pride in this deed of his, but I heard the Messenger of Allah (peace and blessings be upon him) say that the rebellious group will kill him. After hearing this hadith from him, Sayyiduna Muawiyah (may Allah be pleased with him) said: If this is the case, then why do you support us? He replied: My father had complained about me to the Messenger of Allah (peace and blessings be upon him), so the Messenger of Allah (peace and blessings be upon him) said to me: As long as your father is alive, continue to obey him. Because of this hadith, I am with you people, but still, I do not take part in the fighting.
