رَوَى عَبْدُ اَللَّهِ بْنُ أَبِي يَعْفُورٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: "إِذَا رَضِيَ صَاحِبُ اَلْحَقِّ بِيَمِينِ اَلْمُنْكِرِ لِحَقِّهِ فَاسْتَحْلَفَهُ فَحَلَفَ أَنْ لاَ حَقَّ لَهُ قِبَلَهُ ذَهَبَتِ اَلْيَمِينُ بِحَقِّ اَلْمُدَّعِي وَ لاَ دَعْوَى لَهُ" قُلْتُ وَ إِنْ كَانَتْ لَهُ بَيِّنَةٌ عَادِلَةٌ قَالَ "نَعَمْ وَ إِنْ أَقَامَ بَعْدَ مَا اِسْتَحْلَفَهُ بِاللَّهِ خَمْسِينَ قَسَامَةً مَا كَانَ لَهُ حَقٌّ فَإِنَّ اَلْيَمِينَ قَدْ أَبْطَلَتْ كُلَّ مَا اِدَّعَاهُ قَبْلَهُ مِمَّا قَدِ اِسْتَحْلَفَهُ عَلَيْهِ".
Abdullah bin Abi Ya'fur narrated from Abu Abdullah (a.s), who said: "If the claimant is satisfied with the oath of the defendant regarding his claim, and he requests the defendant to swear, and the defendant swears that there is no right due to the claimant upon him, then the oath nullifies the claimant's right, and he no longer has a claim." I said: "What if the claimant has a just and valid proof?" Imam (a.s) said: "Yes, even if he later presents fifty witnesses after having requested the defendant to swear by Allah (swt), he would have no right, for the oath has invalidated all previous claims for which he had requested the defendant to swear."
