Abush Shammakh al-Azdi was told by a cousin of his on his father’s side who was a companion of the Prophet (ﷺ) that he had gone to Mu'awiya, entered his presence and told him he had heard Allah's Messenger ﷺ 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, Allah 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.” Baihaqi transmitted in Shuab al iman.
