Out of the ahadith which Abu Huraira (Allah be pleased with him) reported to us from Messenger of Allah ﷺ one is this that Messenger of Allah ﷺ said: If one among you buys a she-camel having its udder tied up he has the two options for him after milking it either (to retain it) or return it with a sa' of dates.  

عَنْ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ قَالَ رَسُولُ اللَّهِ ﷺ إِذَا مَا أَحَدُكُمُ اشْتَرَى لِقْحَةً مُصَرَّاةً أَوْ شَاةً مُصَرَّاةً فَهُوَ بِخَيْرِ النَّظَرَيْنِ بَعْدَ أَنْ يَحْلُبَهَا إِمَّا هِيَ وَإِلاَّ فَلْيَرُدَّهَا وَصَاعًا مِنْ تَمْرٍ  

[Machine] "And the Messenger of Allah ﷺ said, 'When any one of you buys a pregnant she-camel or a pregnant ewe, then he is considered to have made the better choice out of two options, after milking it. If not, then he should return it and take a measure of dates.'"  

وَقَالَ رَسُولُ اللهِ ﷺ إِذَا مَا أَحَدُكُمُ اشْتَرَى لِقْحَةً مُصَرَّاةً أَوْ شَاةً مُصَرَّاةً فَهُوَ بِخَيْرِ النَّظَرَيْنِ بَعْدَ أَنْ يَحْلُبَهَا إِمَّاهِي وَإِلَّا فَلْيَرُدَّهَا وَصَاعًا مِنْ تَمْرٍ  

Out of the ahadith which Abu Huraira (Allah be pleased with him) reported to us from Messenger of Allah ﷺ one is this that Messenger of Allah ﷺ said: If one among you buys a she-camel having its udder tied up he has the two options for him after milking it either (to retain it) or return it with a sa' of dates. (Using translation from Muslim 1524f)   

"إذَا ما اشترى أحدُكُمْ لَقِحةً مُصَرَّاةً أوْ شاةً مُصراةً فَهُو بخيرِ النَّظَرينِ بعد أنْ يحلبَها: إمَّا هي، وإلَّا فليرُدَّها وصاعا مِنْ تَمْرٍ".
