Abdullah bin 'Awn bin Artaban عبد الله بن عون بن أرطبان الخزار · The Book of Agriculture

"I asked Rafi' bin Khadij about leasing land. He said: 'The Messenger of Allah forbade leasing land.' I said: 'For gold or silver?' He said: 'No, rather he forbade leasing it in return for what the land produces. As for gold and silver, there is nothing wrong with that.'"

"I asked Rafi' bin Khadij about leasing uncultivated land in return for gold and silver. He said: '(It is) permissible and there is nothing wrong with that. That is the due of the land.'"

"I heard Ibn 'Umar say: 'We did not see anything wrong with Al-Khibr until last year, when Rafi' said that the Prophet of Allah forbade it.'"
