Hanzala bin Khulaid says that once I was sitting with Sayyiduna Amir Muawiyah (may Allah be pleased with him) when two men came to him with a dispute. Each of them claimed that he had martyred Sayyiduna Ammar (may Allah be pleased with him). Sayyiduna Ibn Amr (may Allah be pleased with him) said: "You should congratulate each other, for I heard the Noble Prophet (peace and blessings be upon him) say that Ammar will be killed by a rebellious group." Sayyiduna Amir Muawiyah (may Allah be pleased with him) said: "Then what are you doing with us?" He replied: "Once my father complained about me to the Noble Prophet (peace and blessings be upon him), and the Noble Prophet (peace and blessings be upon him) said: 'Obey your father throughout your life, do not disobey him.' That is why I am with you, but I do not participate in the fighting."
