حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا وَكِيعٌ، عَنْ حَمَّادِ بْنِ سَلَمَةَ، عَنْ مُحَمَّدِ بْنِ زِيَادٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ مَنِ اشْتَرَى مُصَرَّاةً فَهُوَ بِالْخِيَارِ إِذَا حَلَبَهَا إِنْ شَاءَ رَدَّهَا وَرَدَّ مَعَهَا صَاعًا مِنْ تَمْرٍ ‏" ‏ ‏.‏ قَالَ أَبُو عِيسَى وَفِي الْبَابِ عَنْ أَنَسٍ وَرَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم ‏.‏
