“If the people were given what they claimed, some would have claimed the lives and property of men. But the one the claim is made against is obliged to swear an oath.”  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَوْ يُعْطَى النَّاسُ بِدَعْوَاهُمُ ادَّعَى نَاسٌ دِمَاءَ رِجَالٍ وَأَمْوَالَهُمْ وَلَكِنِ الْيَمِينُ عَلَى الْمُدَّعَى عَلَيْهِ  

“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
