Narrated `Abdullah:The Prophet (ﷺ) said, "If somebody on the demand of a judge takes an oath to grab (a Muslim's) property and he is liar in it, he will meet Allah Who will be angry with him". So Allah revealed,:-- 'Verily! those who purchase a small gain at the cost of Allah's Covenant and their oaths..' (3.77) 'Al- Ashath came while `Abdullah was narrating (this) to the people. Al-Ashath said, "This verse was revealed regarding me and another man with whom I had a quarrel about a well. The Prophet (ﷺ) said (to me), "Do you have any evidence?' I replied, 'No.' He said, 'Let your opponent take an oath.' I said: I am sure he would take a (false) oath." Thereupon it was revealed: 'Verily! those who purchase a small gain at the cost of Allah's Covenant....' (3.77) (See Hadith No. 72, Vol 6).
حَدَّثَنَا إِسْحَاقُ بْنُ نَصْرٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، وَالأَعْمَشِ، عَنْ أَبِي وَائِلٍ، قَالَ قَالَ عَبْدُ اللَّهِ قَالَ النَّبِيُّ صلى الله عليه وسلم " لاَ يَحْلِفُ عَلَى يَمِينِ صَبْرٍ، يَقْتَطِعُ مَالاً وَهْوَ فِيهَا فَاجِرٌ، إِلاَّ لَقِيَ اللَّهَ وَهْوَ عَلَيْهِ غَضْبَانُ ". فَأَنْزَلَ اللَّهُ {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ} الآيَةَ. فَجَاءَ الأَشْعَثُ وَعَبْدُ اللَّهِ يُحَدِّثُهُمْ فَقَالَ فِيَّ نَزَلَتْ وَفِي رَجُلٍ خَاصَمْتُهُ فِي بِئْرٍ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " أَلَكَ بَيِّنَةٌ ". قُلْتُ لاَ. قَالَ " فَلْيَحْلِفْ ". قُلْتُ إِذًا يَحْلِفُ. فَنَزَلَتْ {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ} الآيَةَ.
