Sahih al-Bukhari 2356, 2357
Narrated `Abdullah (bin Mas`ud):
The Prophet (ﷺ) said, "Whoever takes a false oath to deprive somebody of his property will meet Allah 
while He will be angry with him." Allah revealed: 'Verily those who purchase a little gain at the cost 
of Allah's covenant, and their oaths.' ........(3.77) 
Al-Ashath came (to the place where `Abdullah was narrating) and said, "What has Abu `Abdur- 
Rahman (i.e. `Abdullah) been telling you? This verse was revealed concerning me. I had a well in the 
land of a cousin of mine. The Prophet (ﷺ) asked me to bring witnesses (to confirm my claim). I said, 'I 
don't have witnesses.' He said, 'Let the defendant take an oath then.' I said, 'O Allah's Messenger (ﷺ)! He will 
take a (false) oath immediately.' Then the Prophet (ﷺ) mentioned the above narration and Allah revealed 
the verse to confirm what he had said." (See Hadith No. 692)
حَدَّثَنَا عَبْدَانُ، عَنْ أَبِي حَمْزَةَ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ مَنْ حَلَفَ عَلَى يَمِينٍ يَقْتَطِعُ بِهَا مَالَ امْرِئٍ، هُوَ عَلَيْهَا فَاجِرٌ، لَقِيَ اللَّهَ وَهْوَ عَلَيْهِ غَضْبَانُ‏"‏ فَأَنْزَلَ اللَّهُ تَعَالَى ‏{‏إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلاً‏}‏ الآيَةَ‏.‏ فَجَاءَ الأَشْعَثُ فَقَالَ مَا حَدَّثَكُمْ أَبُو عَبْدِ الرَّحْمَنِ، فِيَّ أُنْزِلَتْ هَذِهِ الآيَةُ، كَانَتْ لِي بِئْرٌ فِي أَرْضِ ابْنِ عَمٍّ لِي فَقَالَ لِي ‏"‏ شُهُودَكَ ‏"‏‏.‏ قُلْتُ مَا لِي شُهُودٌ‏.‏ قَالَ ‏"‏ فَيَمِينَهُ ‏"‏‏.‏ قُلْتُ يَا رَسُولَ اللَّهِ إِذًا يَحْلِفَ‏.‏ فَذَكَرَ النَّبِيُّ صلى الله عليه وسلم هَذَا الْحَدِيثَ، فَأَنْزَلَ اللَّهُ ذَلِكَ تَصْدِيقًا لَهُ‏.‏
