Allah's Messenger (ﷺ) said: "Allah, the Great and Glorious, has said, "There are three whose adversary I shall be on the Day of Resurrection: A man who gave a promise in My Name and then betrayed; a man who sold a free man and consumed his price; and a man who hired a worker and, after receiving full service from him, did not give him his wages.'" [Reported by Muslim].
