What did the Prophet Muhammad (saw) forbid regarding the renting of fields?
 Narrated Az-Zuhri:                     Salim bin `Abdullah told me that Rafi` bin Khadij told `Abdullah bin `Umar that his two paternal uncles who had fought in the battle of Badr informed him that Allah's Apostle forbade the renting of fields. I said to Salim, "Do you rent your land?" He said, "Yes, for Rafi` is mistaken."
