A Jew and I shared some land and he denied my right, so I took him to the holy prophet ﷺ. The holy prophet ﷺ said to me: Have you have proof. I said: No. He then said to the Jew: Swear an oath I said Messenger of Allah,he will swear an oath and go off my property. So Allah sent down: “Those who barter for a small price Allah’s covenant and their oaths...." to the end of the verse.  

كَانَ بَيْنِي وَبَيْنَ رَجُلٍ مِنَ الْيَهُودِ أَرْضٌ فَجَحَدَنِي فَقَدَّمْتُهُ إِلَى النَّبِيِّ ﷺ قَالَ لِيَ النَّبِيُّ ﷺ أَلَكَ بَيِّنَةٌ قُلْتُ لاَ قَالَ لِلْيَهُودِيِّ احْلِفْ قُلْتُ يَا رَسُولَ اللَّهِ إِذًا يَحْلِفَ وَيَذْهَبَ بِمَالِي فَأَنْزَلَ اللَّهُ { إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ } إِلَى آخِرِ الآيَةِ  

“There was a dispute between myself and a Jewish man concerning some land, and he denied me my rights so I brought him to the Prophet ﷺ. The Messenger of Allah ﷺ said to me: 'Do you have proof' I said: 'No.’ He said to the Jews, 'Swear an oath.' I said: 'If he swears an oath he will take my property.' Then Allah, Glorious is He, revealed: 'Verily, those who purchase a small gain at the cost of Allah's covenant and their oaths, they shall have no portion in the Hereafter (Paradise). Neither will Allah neither speak to them nor look at them on the Day of Resurrection nor will He purifies them, and they shall have a painful torment.'”  

كَانَ بَيْنِي وَبَيْنَ رَجُلٍ مِنَ الْيَهُودِ أَرْضٌ فَجَحَدَنِي فَقَدَّمْتُهُ إِلَى النَّبِيِّ ﷺ فَقَالَ لِي رَسُولُ اللَّهِ ﷺ هَلْ لَكَ بَيِّنَةٌ قُلْتُ لاَ قَالَ لِلْيَهُودِيِّ احْلِفْ قُلْتُ إِذًا يَحْلِفَ فَيَذْهَبَ بِمَالِي فَأَنْزَلَ اللَّهُ سُبْحَانَهُ {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلاً} إِلَى آخِرِ الآيَةِ  

[Machine] In this verse, it was revealed to me that I had a piece of land in the possession of my paternal uncle. So, I went to the Messenger of Allah ﷺ and he said, "Do you want me to arbitrate or shall I uphold his oath?" I said, "If he has taken an oath, then you should arbitrate, O Messenger of Allah." So, the Messenger of Allah ﷺ said, "Whoever takes an oath, while he is still a sinner and uses it to wrongfully take the wealth of a Muslim, he will meet Allah while He is angry with him." So, Allah revealed the verse: "Indeed, those who exchange the covenant of Allah and their [own] oaths for a small price..." until the end of the verse.  

فِيَّ أُنْزِلَتْ هَذِهِ الْآيَةُ كَانَتْ لِي أَرْضٌ فِي يَدِ عَمٍّ لِي فَأَتَيْتُ رَسُولَ اللهِ ﷺ فَقَالَ «بَيِّنَتُكَ أَوْ يَمِينُهُ» قُلْتُ يَحْلِفُ إِذًا يَا رَسُولَ اللهِ فَقَالَ رَسُولُ اللهِ ﷺ «مَنْ حَلَفَ عَلَى يَمِينٍ صَبْرٍ يَقْتَطِعُ بِهَا مَالَ امْرِئٍ مُسْلِمٍ وَهُوَ فِيهَا فَاجِرٌ لَقِيَ اللهَ ﷻ وَهُوَ عَلَيْهِ غَضْبَانُ» فَأَنْزَلَ اللهُ ﷻ الْآيَةَ {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلًا} إِلَى آخِرِ الْآيَةِ
