حَدَّثَنَا إِسْحَاقُ بْنُ نَصْرٍ ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ ، أَخْبَرَنَا سُفْيَانُ ، عَنْ مَنْصُورٍ ، وَالْأَعْمَشِ ، عَنْ أَبِي وَائِلٍ ، قَالَ : قَالَ عَبْدُ اللَّهِ ، قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لَا يَحْلِفُ عَلَى يَمِينِ صَبْرٍ يَقْتَطِعُ مَالًا وَهُوَ فِيهَا فَاجِرٌ إِلَّا لَقِيَ اللَّهَ وَهُوَ عَلَيْهِ غَضْبَانُ ، فَأَنْزَلَ اللَّهُ : إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلا سورة آل عمران آية 77 .

So Allah revealed,:-- 'Verily! those who purchase a small gain at the cost of Allah's Covenant and their oaths..' (3.77)
