Arabic (Original)
وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا مَا أَحَدُكُمْ اشْتَرَى لِقْحَةً مُصَرَّاةً أَوْ شَاةً مُصَرَّاةً فَهُوَ بِخَيْرِ النَّظَرَيْنِ بَعْدَ أَنْ يَحْلُبَهَا إِمَّا يَرْضَى وَإِلَّا فَلْيَرُدَّهَا وَصَاعًا مِنْ تَمْرٍ.
English Translation
The Messenger of Allah (peace be upon him) said: 'When one of you buys a she-camel or a sheep whose milk has been left to accumulate in its udder to deceive the buyer, he has the better of two options after milking it: if he is satisfied, he keeps it; otherwise, he returns it along with a sa' of dates.'
