Abu Umayyah Amr bin Yahya bin Sa'id reports that I heard my grandfather Sa'id bin Amr bin Sa'id bin 'As narrate that Sayyiduna Abu Hurairah (may Allah be pleased with him) used to carry a water vessel and walk alongside the Messenger of Allah (peace and blessings be upon him). When he fell ill, after him, Sayyiduna Mu'awiyah (may Allah be pleased with him) would carry that vessel and walk alongside the Messenger of Allah (peace and blessings be upon him). On one occasion, Sayyiduna Mu'awiyah (may Allah be pleased with him) was helping the Messenger of Allah (peace and blessings be upon him) perform ablution, when the Prophet (peace and blessings be upon him) looked up at him once or twice and said: "Mu'awiyah! If you are ever made a leader, then fear Allah and act with justice." Sayyiduna Mu'awiyah (may Allah be pleased with him) said: After hearing this statement, I was certain that I would definitely be given leadership (because whatever the Prophet, peace and blessings be upon him, said would surely come to pass).
