Not paying honestly


Narrated Abu Huraira:

The Prophet (ﷺ) said, “Allah said, ‘I will be an opponent to three types of people on the Day of Resurrection: -1. One who makes a covenant in My Name, but proves treacherous; -2. One who sells a free person and eats his price; and -3. One who employs a laborer and takes full work from him but does not pay him for his labor.’ ”
