Abu Abd Rabb narrates: I heard Sayyiduna Mu'awiyah (may Allah be pleased with him) say on the pulpit: I heard the Messenger of Allah (peace and blessings be upon him) say: "Nothing remains of this world except trial and tribulation. The example of each one of you is like a vessel: when its top is pure, its bottom is pure too."
