باب النَّهْىِ عَنِ الْمُصَرَّاةِ، وَهُوَ أَنْ يَرْبِطَ، أَخْلاَفَ النَّاقَةِ أَوِ الشَّاةِ وَتُتْرَكُ مِنَ الْحَلْبِ يَوْمَيْنِ وَالثَّلاَثَةَ حَتَّى يَجْتَمِعَ لَهَا لَبَنٌ فَيَزِيدَ مُشْتَرِيهَا فِي قِيمَتِهَا لِمَا يَرَى مِنْ كَثْرَةِ لَبَنِهَا ‏.‏
Sunan an-Nasa'i 4488
It was narrated from Abu Hurairah that the Messenger of Allah said:
"whoever buys a Musarraha, if he is please with it when he milks it, he may keep it, and if he is not please with it, he may return it, along with a Sa of daters"' (Sahih )
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْحَارِثِ، قَالَ حَدَّثَنِي دَاوُدُ بْنُ قَيْسٍ، عَنِ ابْنِ يَسَارٍ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنِ اشْتَرَى مُصَرَّاةً فَإِنْ رَضِيَهَا إِذَا حَلَبَهَا فَلْيُمْسِكْهَا وَإِنْ كَرِهَهَا فَلْيَرُدَّهَا وَمَعَهَا صَاعٌ مِنْ تَمْرٍ ‏"‏ ‏.‏
