ثنا أَبُو بَكْرٍ النَّيْسَابُورِيُّ ، نَا يُونُسُ بْنُ عَبْدِ الأَعْلَى ، نَا ابْنُ وَهْبٍ ، أنا اللَّيْثُ ، أَنَّ نَافِعًا ، حَدَّثَهُ ، عَنِ ابْنِ عُمَرَ ، أَنّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " إِذَا تَبَايَعَ الرَّجُلانِ فَكُلُّ وَاحِدٍ مِنْهُمَا بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا وَكَانَا جَمِيعًا ، أَوْ يُخَيِّرُ أَحَدُهُمَا الآخَرَ فَيَتَبَايَعَانِ عَلَى ذَلِكَ ، فَقَدْ وَجَبَ الْبَيْعُ " ،.
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) said: "When two men make a transaction, each of them has the option (to cancel it) as long as they have not separated from each other and are together, or until one of them gives the option to the other. When they make the transaction in this manner, then the transaction becomes binding."
