‘Amr b. Murra told that he said to Mu'awiya he had heard God’s Messenger say, "If anyone is put by God in authority over any matter concerning the Muslims and turns away from dealing with their need, destitution and poverty, God will turn away from dealing with his need, destitution and poverty.” Mu'awiya then appointed a man to deal with the needs of the people.
Abu Dawud and Tirmidhi transmitted it. A version by Ahmad and Tirmidhi has, “God will lock the gates of heaven upon his destitution, need and poverty.”
Abu Sa'id reported the Prophet as saying, “Every perfidious one will have a standard at his anus on the day of resurrection.” A version has, “On the day of resurrection every perfidious one will have a standard which will be raised for him according to the amount of his perfidy, and no one is more perfidious than the ruler of a community.”
Abush Shammakh al-Azdi was told by a cousin of his on his father’s side who was a companion of the Prophet that he had gone to Mu'awiya, entered his presence and told him he had heard God's Messenger say, "If one who has been given any authority over the people locks his gate against Muslims, or one who has been wronged, or one who has a need, God will lock the gates of His mercy against him when he has a need or is in poverty, however much he is in need of Him.”
