Sahih al-Bukhari 2227
Narrated Abu Huraira:
The Prophet ﷺ said, "Allah says, 'I will be against three persons on the Day of Resurrection: 1. One who makes a covenant in My Name, but he proves treacherous. 2. One who sells a free person (as a slave) and eats the price, 3. And one who employs a laborer and gets the full work done by him but does not pay him his wages.' "
حَدَّثَنِي بِشْرُ بْنُ مَرْحُومٍ، حَدَّثَنَا يَحْيَى بْنُ سُلَيْمٍ، عَنْ إِسْمَاعِيلَ بْنِ أُمَيَّةَ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ ﷺ قَالَ " قَالَ اللَّهُ ثَلاَثَةٌ أَنَا خَصْمُهُمْ يَوْمَ الْقِيَامَةِ، رَجُلٌ أَعْطَى بِي ثُمَّ غَدَرَ، وَرَجُلٌ بَاعَ حُرًّا فَأَكَلَ ثَمَنَهُ، وَرَجُلٌ اسْتَأْجَرَ أَجِيرًا فَاسْتَوْفَى مِنْهُ، وَلَمْ يُعْطِ أَجْرَهُ ".
