Abu Dawud Book 13, Hadith Number 2942.
Chapter : Not known.
Narated By AbuMaryam al-Azdi : When I entered upon Mu’awiyah, he said: How good your visit is to us, O father of so-and-so. (This is an idiom used by the Arabs on such occasions). I said: I tell you a tradition which I heard (from the Prophet). I heard the Apostle of Allah (PBUH) say: If Allah puts anyone in the position of authority over the affairs of the Muslims, and he secludes himself (from them), not fulfilling their needs, wants, and poverty, Allah will keep Himself away from him, not fulfilling his need, want and poverty. He said: He (Mu’awiyah) appointed a man to fulfil the needs of the people.
