Chapter: The sin of a person who sells a free man

The Prophet (ﷺ) said, "Allah says, 'I will be against three persons on the Day of Resurrection: -1. One who makes a covenant in My Name, but he proves treacherous. -2. One who sells a free person (as a slave) and eats the price, -3. And one who employs a laborer and gets the full work done by him but does not pay him his wages.' "
