Sahih al-Bukhari 6676, 6677
Narrated `Abdullah:
Allah's Messenger (ﷺ) said, "If somebody is ordered (by the ruler or the judge) to take an oath, and he takes a 
false oath in order to grab the property of a Muslim, then he will incur Allah's Wrath when he will 
meet Him." And Allah revealed in its confirmation: 'Verily! Those who purchase a small gain at the 
cost of Allah's covenants and their own oaths.' (3.77) (The sub-narrator added:) Al-Ash'ath bin Qais 
entered, saying, "What did Abu `Abdur-Rahman narrate to you?" They said, "So-and-so," Al-Ash'ath 
said, "This verse was revealed in my connection. I had a well on the land of my cousin (and we had a 
dispute about it). I reported him to Allah 's Apostle who said (to me). "You should give evidence (i.e. 
witness) otherwise the oath of your opponent will render your claim invalid." I said, "Then he (my 
opponent) will take the oath, O Allah's Messenger (ﷺ)." Allah's Messenger (ﷺ) said, "Whoever is ordered (by the 
ruler or the judge) to give an oath, and he takes a false oath in order to grab the property of a Muslim, 
then he will incur Allah's Wrath when he meets Him on the Day of Resurrection."
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنْ حَلَفَ عَلَى يَمِينِ صَبْرٍ، يَقْتَطِعُ بِهَا مَالَ امْرِئٍ مُسْلِمٍ، لَقِيَ اللَّهَ وَهْوَ عَلَيْهِ غَضْبَانُ ‏"‏‏.‏ فَأَنْزَلَ اللَّهُ تَصْدِيقَ ذَلِكَ ‏{‏إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلاً‏}‏ إِلَى آخِرِ الآيَةِ‏.‏   فَدَخَلَ الأَشْعَثُ بْنُ قَيْسٍ فَقَالَ مَا حَدَّثَكُمْ أَبُو عَبْدِ الرَّحْمَنِ، فَقَالُوا كَذَا وَكَذَا‏.‏ قَالَ فِيَّ أُنْزِلَتْ، كَانَتْ لِي بِئْرٌ فِي أَرْضِ ابْنِ عَمٍّ لِي فَأَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏"‏ بَيِّنَتُكَ أَوْ يَمِينُهُ ‏"‏‏.‏ قُلْتُ إِذًا يَحْلِفُ عَلَيْهَا يَا رَسُولَ اللَّهِ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنْ حَلَفَ عَلَى يَمِينِ صَبْرٍ، وَهْوَ فِيهَا فَاجِرٌ، يَقْتَطِعُ بِهَا مَالَ امْرِئٍ مُسْلِمٍ، لَقِيَ اللَّهَ يَوْمَ الْقِيَامَةِ، وَهْوَ عَلَيْهِ غَضْبَانُ ‏"‏‏.‏
