Narrated Abu Huraira:


The Prophet () said, "Allah said, 'I will be an opponent to three types of people on the Day of Resurrection: -1. One who makes a covenant in My Name, but proves treacherous; -2. One who sells a free person and eats his price; and -3. One who employs a laborer and takes full work from him but does not pay him for his lab our.' "

حَدَّثَنَا يُوسُفُ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنِي 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 تَعَالَى ثَلاَثَةٌ أَنَا خَصْمُهُمْ يَوْمَ الْقِيَامَةِ رَجُلٌ أَعْطَى بِي ثُمَّ غَدَرَ، وَرَجُلٌ بَاعَ حُرًّا فَأَكَلَ ثَمَنَهُ، وَرَجُلٌ اسْتَأْجَرَ أَجِيرًا فَاسْتَوْفَى مِنْهُ وَلَمْ يُعْطِهِ أَجْرَهُ ‏"‏‏.‏
