قَالَ يَحْيَى قَالَ مَالِكٌ عَنْ جَمِيلِ بْنِ عَبْدِ الرَّحْمَنِ الْمُؤَذِّنِ، أَنَّهُ كَانَ يَحْضُرُ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ وَهُوَ يَقْضِي بَيْنَ النَّاسِ فَإِذَا جَاءَهُ الرَّجُلُ يَدَّعِي عَلَى الرَّجُلِ حَقًّا نَظَرَ فَإِنْ كَانَتْ بَيْنَهُمَا مُخَالَطَةٌ أَوْ مُلاَبَسَةٌ أَحْلَفَ الَّذِي ادُّعِيَ عَلَيْهِ وَإِنْ لَمْ يَكُنْ شَىْءٌ مِنْ ذَلِكَ لَمْ يُحَلِّفْهُ . قَالَ مَالِكٌ وَعَلَى ذَلِكَ الأَمْرُ عِنْدَنَا أَنَّهُ مَنِ ادَّعَى عَلَى رَجُلٍ بِدَعْوَى نُظِرَ فَإِنْ كَانَتْ بَيْنَهُمَا مُخَالَطَةٌ أَوْ مُلاَبَسَةٌ أُحْلِفَ الْمُدَّعَى عَلَيْهِ فَإِنْ حَلَفَ بَطَلَ ذَلِكَ الْحَقُّ عَنْهُ وَإِنْ أَبَى أَنْ يَحْلِفَ وَرَدَّ الْيَمِينَ عَلَى الْمُدَّعِي فَحَلَفَ طَالِبُ الْحَقِّ أَخَذَ حَقَّهُ .
Yahya said that Malik spoke about a man who died and had a debt owing to him and there was one witness, and some people had a debt against him and they had only one witness, and his heirs refused to take an oath on their rights with their witness. He said, "The creditors take an oath and take their rights. If there is anything left over, the heirs do not take any of it. That is because the oaths were offered to them before and they abandoned them, unless they say, 'We did not know that our companion had extra,' and it is known that they only abandoned the oaths because of that. I think that they should take an oath and take what remains after his debt." Yahya said, "Malik said about Jamil ibn Abd ar-Rahman al-Muadhdin that he was present with Umar ibn Abd al-Aziz when he was judging between people. If a man came to him with a claim against a man, he examined whether or not there were frequent transactions and dealings between them. If there were, the defendant could make an oath. If there was nothing of that nature he did not accept an oath from him." Malik summed up, "What is done in our community is that if some one makes a claim against a man, it is examined. If there are frequent transactions and dealings between them, the defendant is made to take an oath. If he takes an oath, the claim against him is dropped. If the defendant refuses to take an oath, and returns the oath to the claimant, the one claiming his right takes an oath and takes his due
