Narrated Abu Huraira:
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 صلى الله عليه وسلم 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 " .
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.' "
