Abu Umayyah Amr bin Yahya bin Saeed says: I heard from my grandfather, who narrated that Sayyiduna Abu Hurairah (may Allah be pleased with him) fell ill, and after him, Sayyiduna Muawiyah (may Allah be pleased with him) took charge of the ablution vessel and began to accompany the Messenger of Allah (peace and blessings be upon him) with that vessel. One day, he was helping you (peace and blessings be upon him) perform ablution, when you (peace and blessings be upon him) raised your blessed head towards him once or twice and said: "Muawiyah! If you are given authority, then always fear Allah and hold fast to justice." Sayyiduna Muawiyah (may Allah be pleased with him) said: In view of this statement of the Noble Prophet (peace and blessings be upon him), I was certain that I would be tested in the matter of authority, and eventually, that is what happened.
