Abu Huraira (Allah be pleased with him) reported Messenger of Allah ﷺ as saying: He who buys a goat having its udder tied up has two courses left for him. He may retain it, and if he desires may return it along with a sa' of dates and not wheat.

حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنِ اشْتَرَى شَاةً مُصَرَّاةً فَهُوَ بِخَيْرِ النَّظَرَيْنِ إِنْ شَاءَ أَمْسَكَهَا وَإِنْ شَاءَ رَدَّهَا وَصَاعًا مِنْ تَمْرٍ لاَ سَمْرَاءَ " .
