[Machine] I accompanied the Messenger of Allah ﷺ and we came across a situation like this. The seller was instructed to take an oath, and then the buyer was given the choice to either take it or leave it. If he wished, he could take it, and if he wished, he could leave it. This narration is from Abdullah bin Ahmad who said that Ahmadd ibn Hanbal informed me about Hisham bin Yusuf, who narrated from Ibn Juraij, who narrated from Isma'il bin Umayyah, who narrated from Abd al-Malik bin Ubaid, who said that Hajjaj al-Awar narrated from Abd al-Malik bin Ubaidah 10808. Abu Abdullah al-Hafiz informed us, who was narrated by Abu Bakr bin Ishaq al-Faqih, who was narrated by Abdullah bin Ahmad bin Hanbal, who narrated it from my father and mentioned the narration.  

حَضَرْتُ رَسُولَ اللهِ ﷺ أُتِيَ فِي مِثْلِ هَذَا فَأَمَرَ الْبَائِعَ أَنْ يُسْتَحْلَفَ ثُمَّ لِيُخَيَّرَ الْمُبْتَاعُ فَإِنْ شَاءَ أَخَذَ وَإِنْ شَاءَ تَرَكَ زَادَ فِيهِ غَيْرُهُ عَنْ عَبْدِ اللهِ بْنِ أَحْمَدَ قَالَ عَبْدُ اللهِ قَالَ أَحْمَدُ أُخْبِرْتُ عَنْ هِشَامِ بْنِ يُوسُفَ عَنِ ابْنِ جُرَيْجٍ عَنْ إِسْمَاعِيلَ بْنِ أُمَيَّةَ عَنْ عَبْدِ الْمَلِكِ بْنِ عُبَيْدٍ قَالَ أَحْمَدُ وَقَالَ حَجَّاجٌ الْأَعْوَرُ عَبْدُ الْمَلِكِ بْنُ عُبَيْدَةَ 10808 أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو بَكْرِ بْنُ إِسْحَاقَ الْفَقِيهُ ثنا عَبْدُ اللهِ بْنُ أَحْمَدَ بْنِ حَنْبَلٍ حَدَّثَنِي أَبِي فَذَكَرَهُ
