"O Banu Harithah, a calamity has befallen you." They said: "What is it?" He said: "The Messenger of Allah has forbidden leasing land." We said: "O Messenger of Allah, what if we lease it in return for some of the grain?" He said, "No." He said: "We used to lease it in return for straw." He said: "No." "We used to lease it in return for what is planted on the banks of a stream that is used for irrigation." He said: "No. Cultivate it (yourself) or give it to your brother."
