[Machine] The Messenger of Allah ﷺ said, "The two parties involved in a transaction have the option to cancel it until they separate, or the transaction is of a good choice." He said, "And perhaps one of them says to the other, 'Choose.'"  

البيهقي:١٠٤٥٥ – مَا أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أنا أَبُو عَبْدِ اللهِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا مُحَمَّدُ بْنُ إِسْحَاقَ ثنا عَلِيُّ بْنُ حُجْرٍ قَالَ وَأَخْبَرَنِي أَبُو عَمْرِو بْنُ أَبِي جَعْفَرٍ ثنا عَبْدُ اللهِ بْنُ مُحَمَّدٍ ثنا عَمْرُو بْنُ زُرَارَةَ قَالَا ثنا إِسْمَاعِيلُ بْنُ عُلَيَّةَ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ

قَالَ رَسُولُ اللهِ ﷺ الْبَيِّعَانِ بِالْخِيَارِ حَتَّى يَتَفَرَّقَا أَوْ يَكُونَ بَيْعَ خِيَارٍ قَالَ وَرُبَّمَا قَالَ نَافِعٌ أَوْ يَقُولُ أَحَدُهُمَا لِلْآخَرِ اخْتَرْ
