What did the Prophet Muhammad (peace be upon him) say about buying a sheep that has been kept unmilked for a long period?
 Narrated Abu Huraira:                     Allah's Apostle said, "Whoever buys a sheep which has been kept unmilked for a long period, and milks it, can keep it if he is satisfied, and if he is not satisfied, he can return it, but he should pay one Sa of dates for the milk."
