وَعَنْ أَبِي هُرَيْرَةَ رضى الله عنه عَنِ
النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَا تَصُرُّوا اَلْإِبِلَ وَالْغَنَمَ، فَمَنِ اِبْتَاعَهَا بَعْدُ فَإِنَّهُ بِخَيْرِ اَلنَّظَرَيْنِ بَعْدَ أَنْ يَحْلُبَهَا، إِنْ شَاءَ أَمْسَكَهَا، وَإِنْ شَاءَ رَدَّهَا وَصَاعًا مِنْ تَمْرٍ»
The Prophet (sallallahu alayhi wa sallam) 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.”.
