Volume 3, Book 34, Number 358:
Narrated Abu Huraira:
The Prophet said, “Don’t keep camels and sheep unmilked for a long time, for whoever buys such
an animal has the option to milk it and then either to keep it or return it to the owner along with one
Sa of dates.” Some narrated from Ibn Sirin (that the Prophet had said), “One Sa of wheat, and he has
the option for three days.” And some narrated from Ibn Sirin, ” … a Sa of dates,” not mentioning the
option for three days. But a Sa of dates is mentioned in most narrations.
