Volume 3, Book 50, Number 883:
Narrated Rafi bin Khadij:
We used to work on the fields more than the other Ansar, and we used to rent the land (for the
yield of a specific portion of it). But sometimes that portion or the rest of the land did not give any
yield, so we were forbidden (by the Prophet ) to follow such a system, but we were allowed to rent
the land for money.
