Sayyiduna Abu Hurairah (may Allah be pleased with him) says: I heard the Messenger of Allah (peace and blessings be upon him) say: "There are three people with whom I will dispute on the Day of Resurrection: one who made a promise to Me in Allah's name and then acted treacherously, one who sold a free man and consumed his price, and one who hired a laborer, took full work from him, but did not pay him his full wages."
