قَالَ مَالِك : الْأَمْرُ عِنْدَنَا فِي الرَّجُلِ يَشْتَرِي السِّلْعَةَ مِنَ الرَّجُلِ فَيَخْتَلِفَانِ فِي الثَّمَنِ، فَيَقُولُ الْبَائِعُ : بِعْتُكَهَا بِعَشَرَةِ دَنَانِيرَ، وَيَقُولُ الْمُبْتَاعُ : ابْتَعْتُهَا مِنْكَ بِخَمْسَةِ دَنَانِيرَ، إِنَّهُ يُقَالُ لِلْبَائِعِ : إِنْ شِئْتَ فَأَعْطِهَا لِلْمُشْتَرِي بِمَا قَالَ، وَإِنْ شِئْتَ فَاحْلِفْ بِاللَّهِ مَا بِعْتَ سِلْعَتَكَ إِلَّا بِمَا قُلْتَ، فَإِنْ حَلَفَ قِيلَ لِلْمُشْتَرِي : إِمَّا أَنْ تَأْخُذَ السِّلْعَةَ بِمَا قَالَ الْبَائِعُ، وَإِمَّا أَنْ تَحْلِفَ بِاللَّهِ مَا اشْتَرَيْتَهَا إِلَّا بِمَا قُلْتَ، فَإِنْ حَلَفَ بَرِئَ مِنْهَا، وَذَلِكَ أَنَّ كُلَّ وَاحِدٍ مِنْهُمَا مُدَّعٍ عَلَى صَاحِبِهِ
Imam Malik, may Allah have mercy on him, said: According to us, the ruling is that if a person buys something from another person, and then there is a dispute regarding the price, the seller says: I sold it for ten dinars, and the buyer says: I bought it for five dinars, then it will be said to the seller: If you wish, give the item to the buyer for five dinars; if not, then swear an oath that: I did not sell my item except for ten dinars. If the seller swears the oath, then it will be said to the buyer: If you wish, take the item for ten dinars; if not, then swear an oath that: I did not buy this item except for five dinars. If the buyer swears this oath, then he will be acquitted, because each of them is a claimant against the other.
