باب كَلاَمِ الْخُصُومِ بَعْضِهِمْ فِي بَعْضٍ
Sahih al-Bukhari 2416, 2417

Narrated `Abdullah bin Mas`ud:

Allah's Messenger (ﷺ) said, "Whoever takes a false oath so as to take the property of a Muslim (illegally) will meet Allah while He will be angry with him." Al-Ash'ath said: By Allah, that saying concerned me. I had common land with a Jew, and the Jew later on denied my ownership, so I took him to the Prophet who asked me whether I had a proof of my ownership. When I replied in the negative, the Prophet asked the Jew to take an oath. I said, "O Allah's Messenger (ﷺ)! He will take an oath and deprive me of my property." So, Allah revealed the following verse: "Verily! Those who purchase a little gain at the cost of Allah's covenant and their oaths." (3.77)

حَدَّثَنَا مُحَمَّدٌ، أَخْبَرَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنْ حَلَفَ عَلَى يَمِينٍ وَهْوَ فِيهَا فَاجِرٌ لِيَقْتَطِعَ بِهَا مَالَ امْرِئٍ مُسْلِمٍ لَقِيَ اللَّهَ وَهْوَ عَلَيْهِ غَضْبَانُ ‏"‏‏.‏ قَالَ فَقَالَ الأَشْعَثُ فِيَّ وَاللَّهِ كَانَ ذَلِكَ، كَانَ بَيْنِي وَبَيْنَ رَجُلٍ مِنَ الْيَهُودِ أَرْضٌ فَجَحَدَنِي، فَقَدَّمْتُهُ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَلَكَ بَيِّنَةٌ ‏"‏‏.‏ قُلْتُ لاَ‏.‏ قَالَ فَقَالَ لِلْيَهُودِيِّ ‏"‏ احْلِفْ ‏"‏‏.‏ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِذًا يَحْلِفَ، وَيَذْهَبَ بِمَالِي، فَأَنْزَلَ اللَّهُ تَعَالَى ‏{‏إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلاً‏}‏ إِلَى آخِرِ الآيَةِ‏.‏
