Hadith 21, 40 Hadith Qudsi
On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (ﷺ) said that Allah the Almighty said:
There are three (1) whose adversary I shall be on the Day of Resurrection: a man who has given his word by Me and has broken it; a man who has sold a free man (2) and has consumed the price; 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).
عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ، عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: 

" قَالَ اللَّهُ تَعَالَى: ثَلَاثَةٌ أَنَا خَصْمُهُمْ يَوْمَ الْقِيَامَةِ: رَجُلٌ أَعْطَى بِي ثُمَّ غَدَرَ (1)، وَرَجُلٌ بَاعَ حُرًّا فَأَكَلَ ثَمَنَهُ، وَرَجُلٌ اسْتَأْجَرَ أَجِيرًا فَاسْتَوْفَى مِنْهُ وَلَمْ يُعْطِهِ أَجْرَهُ" 
رواه البخاري (وكذلك ابن ماجه وأحمد)
