Mishkat al-Masabih 3729

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 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.” Baihaqi transmitted in Shuab al iman.
