Sahih Muslim , Book 10, Hadith 3639 (USC-MSA) ⓘ
Hammam b. Munabbih said: Out of the ahadith which Abu Huraira (Allah be pleased with him) reported to us from Allah's Messenger one is this that Allah's Messenger 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.
حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا مَا أَحَدُكُمُ اشْتَرَى لِقْحَةً مُصَرَّاةً أَوْ شَاةً مُصَرَّاةً فَهُوَ بِخَيْرِ النَّظَرَيْنِ بَعْدَ أَنْ يَحْلُبَهَا إِمَّا هِيَ وَإِلاَّ فَلْيَرُدَّهَا وَصَاعًا مِنْ تَمْرٍ " .
