Volume 3, Book 34, Number 359:
Narrated ‘Abdullah bin Mas’ud:
Whoever buys a sheep which has not been milked for a long time, has the option of returning it
along with one Sa of dates; and the Prophet forbade going to meet the seller on the way (as he has no
knowledge of the market price and he may sell his goods at a low price).
