Narrated Abu Hurairah (RA):

The Prophet (ﷺ) said: "Do not tie up the udders of camels and goats. He who buys them after that (has been done) has two choices open to him after milking them: he may keep them if he wishes, or may return them along with one Sa' of dates." [Agreed upon].

وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- عَنِ النَّبِيِّ ‏- صلى الله عليه وسلم ‏-قَالَ: { لَا تَصُرُّوا اَلْإِبِلَ وَالْغَنَمَ, فَمَنِ اِبْتَاعَهَا بَعْدُ فَإِنَّهُ بِخَيْرِ اَلنَّظَرَيْنِ بَعْدَ أَنْ يَحْلُبَهَا, إِنْ شَاءَ أَمْسَكَهَا, وَإِنْ شَاءَ رَدَّهَا وَصَاعًا مِنْ تَمْرٍ } مُتَّفَقٌ عَلَيْهِ [1]‏ .‏
