Chapter 72 | Dispute between Buyer and Seller
2- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنِ الْحُسَيْنِ بْنِ عُمَرَ بْنِ يَزِيدَ عَنْ أَبِيهِ عَنْ أَبِي عَبْدِ اللهِ قَالَ قَالَ رَسُولُ اللهِ ﷺ إِذَا التَّاجِرَانِ صَدَقَا بُورِكَ لَهُمَا فَإِذَا كَذَبَا وَخَانَا لَمْ يُبَارَكْ لَهُمَا وَهُمَا بِالْخِيَارِ مَا لَمْ يَفْتَرِقَا فَإِنِ اخْتَلَفَا فَالْقَوْلُ قَوْلُ رَبِّ السِّلْعَةِ أَوْ يَتَتَارَكَا.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Al-Husayn ‘Umar ibn Yazid from his father, who has said the following: “Abu ‘Abd Allah , has said, ‘If the two business people speak the truth the transaction is a blessing for them; but if they speak lies and cheat, it does not become a blessing for them. They have the choice to keep or dismiss the transaction as long as they you must not depart each other. After they depart the words of the owner of merchandise are accepted or they can mutually agree to dismiss the transaction.’”
