Chapter 14: Prohibition Of (Selling) al-Musarrah, and It Is To Bind The Udders Of the Camel Or The Sheep, And To Avoid Milking Them For Two Or Three Days, Until the Milk Gathers In Them, Increasing The Profits Of The Sale When It Is Seen That It Has A Great Amount Of Milk - كتاب البيوع
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْحَارِثِ، قَالَ حَدَّثَنِي دَاوُدُ بْنُ قَيْسٍ، عَنِ ابْنِ يَسَارٍ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " مَنِ اشْتَرَى مُصَرَّاةً فَإِنْ رَضِيَهَا إِذَا حَلَبَهَا فَلْيُمْسِكْهَا وَإِنْ كَرِهَهَا فَلْيَرُدَّهَا وَمَعَهَا صَاعٌ مِنْ تَمْرٍ " .
It was narrated from Abu Hurairah that the Messenger of Allah said:
"whoever buys a Musarraha, if he is please with it when he milks it, he may keep it, and if he is not please with it, he may return it, along with a Sa of daters"' (Sahih )
