Allah is adversary to Three types of Man
There are three (*1) whose adversary I shall be on the Day of Resurrection:
1) a man who has given his word by Me and has broken it;
2) a man who has sold a free man (*2) and has consumed the price;
3) and a man who has hired a workman, has exacted his due in full from him and has not given him his wage.(*1) i.e. types of men.
(*2) i.e. a man who has made a slave of another and has sold him.
It was related by al-Bukhari (also by Ibn Majah and Ahmad ibn Hanbal).
