Al-Qasim bin Mukhaymirah narrates from a man of Palestine whose kunyah was Abu Maryam, of the tribe of Asad, that he came to Sayyiduna Mu'awiyah (may Allah be pleased with him). He asked: What has brought you? He said: A hadith that I heard from the Prophet (peace and blessings be upon him); when I saw your position, I came to tell you. I heard the Messenger of Allah (peace and blessings be upon him) saying: "Whomever Allah places in charge of any of the affairs of the people, and he screens himself off from their needs, their wants and their poverty, Allah Almighty will screen Himself off from his need, his want and his poverty on the Day of Resurrection."
