What did the Prophet Muhammad (saw) say about the three types of people who will be opposed by Allah on the Day of Resurrection?
 Narrated Abu Huraira:                     The Prophet 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 lab our.' "
