Narrated Abdullah:

Allah's Apostle ﷺ said, "If somebody takes a false oath in order to get the property of a Muslim (unjustly) by that oath, then Allah will be angry with him when he will meet Him." Al-Ash'ath informed me, "By Allah! This was said regarding me. There was a dispute about a piece of land between me and a man from the Jews who denied my right. I took him to the Prophet. Allah's Apostle asked me, 'Do you have an evidence?' I replied in the negative. He said to the Jew, 'Take an oath.' I said, 'O Allah's Apostle! He will surely take an oath and take my property unjustly." So, Allah revealed: "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 ﷺ " مَنْ حَلَفَ عَلَى يَمِينٍ وَهْوَ فِيهَا فَاجِرٌ، لِيَقْتَطِعَ بِهَا مَالَ امْرِئٍ مُسْلِمٍ، لَقِيَ اللَّهَ وَهْوَ عَلَيْهِ غَضْبَانُ ". قَالَ فَقَالَ الأَشْعَثُ بْنُ قَيْسٍ فِيَّ وَاللَّهِ كَانَ ذَلِكَ، كَانَ بَيْنِي وَبَيْنَ رَجُلٍ مِنَ الْيَهُودِ أَرْضٌ فَجَحَدَنِي، فَقَدَّمْتُهُ إِلَى النَّبِيِّ ﷺ فَقَالَ لِي رَسُولُ اللَّهِ ﷺ " أَلَكَ بَيِّنَةٌ ". قَالَ قُلْتُ لاَ. قَالَ فَقَالَ لِلْيَهُودِيِّ " احْلِفْ ". قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِذًا يَحْلِفَ وَيَذْهَبَ بِمَالِي. قَالَ فَأَنْزَلَ اللَّهُ تَعَالَى {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلاً} إِلَى آخِرِ الآيَةِ.
