باب حُكْمِ بَيْعِ الْمُصَرَّاةِ ‏‏
Sahih Muslim 1524 b

Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:

He who buys a goat with its udder tied up has the option to retain the goat if he so desires or return it within three days, and in case he returns it he should do so along with a sa' of dates.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ الْقَارِيَّ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنِ ابْتَاعَ شَاةً مُصَرَّاةً فَهُوَ فِيهَا بِالْخِيَارِ ثَلاَثَةَ أَيَّامٍ إِنْ شَاءَ أَمْسَكَهَا وَإِنْ شَاءَ رَدَّهَا وَرَدَّ مَعَهَا صَاعًا مِنْ تَمْرٍ ‏"‏ ‏.‏
