Bismillah irRahman irRaheem
In the Name of Allaah, The Most Gracious, The Most Kind

Abu Hurairah (RAA) reported that the messenger of Allah (SAW) said what
translated means:

" Allah says: 'I will be the enemy of three (kinds of) people on the
day of resurrection:

(1) a person who made a covenant in My Name and then broke it,
(2) a person who sold a free person as a slave and consumed his
price, and
(3) a person who hired somebody (to do something) and upon the
completion of the job, he denied him his wages. ' "
