Abu Hurairah (May Allah be pleased with him) reported:
The Prophet ﷺ said, "Allah, the Exalted, says: 'I will contend on the Day of Resurrection against three (types of) people: One who makes a covenant in My Name and then breaks it; one who sells a free man as a slave and devours his price; and one who hires a workman and having taken full work from him, does not pay him his wages."'

[Al-Bukhari].

وعن أبي هريرة رضي الله عنه عن النبي ﷺ قال: " قال الله تعالى: ثلاثة أنا خصمهم يوم القيامة : رجل أعطى بي ثم غدر، ورجل باع حرًا فأكل ثمنه، ورجل استأجر أجيرًا، فاستوفى منه، ولم يعطه أجره" ((رواه البخاري)).
