Narrated Abu Hurairah:The Messenger of Allah (ﷺ) as saying: If anyone buys sheep or goat whose udders have been tied up and he milked it, he may keep it if he is pleased with it, or he may return it if he is displeased with it. There is one sa' of dates (which he must give to the seller) for milking it.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَخْلَدٍ التَّمِيمِيُّ، حَدَّثَنَا الْمَكِّيُّ، - يَعْنِي ابْنَ إِبْرَاهِيمَ - حَدَّثَنَا ابْنُ جُرَيْجٍ، حَدَّثَنِي زِيَادٌ، أَنَّ ثَابِتًا، مَوْلَى عَبْدِ الرَّحْمَنِ بْنِ زَيْدٍ أَخْبَرَهُ أَنَّهُ، سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنِ اشْتَرَى غَنَمًا مُصَرَّاةً احْتَلَبَهَا فَإِنْ رَضِيَهَا أَمْسَكَهَا وَإِنْ سَخِطَهَا فَفِي حَلْبَتِهَا صَاعٌ مِنْ تَمْرٍ " .
