Abu Huraira (Allah be pleased with him) reported Allah's Messenger (may peace be'upon him) as saying: He who bought a goat having its udder tied up should go back with it, milk it, and, if he is satisfied with its milk, he should retair it, otherwise he should return it along with a sa' of dates.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا دَاوُدُ بْنُ قَيْسٍ، عَنْ مُوسَى بْنِ يَسَارٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنِ اشْتَرَى شَاةً مُصَرَّاةً فَلْيَنْقَلِبْ بِهَا فَلْيَحْلُبْهَا فَإِنْ رَضِيَ حِلاَبَهَا أَمْسَكَهَا وَإِلاَّ رَدَّهَا وَمَعَهَا صَاعٌ مِنْ تَمْرٍ " .
