Abdur Rahman bin Khalid عبد الرحمن بن خالد بن مسافر · The Book of Agriculture

"Rafi' bin Khadij came to us and said: 'The Messenger of Allah has forbidden for you Al-Haql. Al-Haql is the third and the fourth. And Al-Muzabanah. Al-Muzabanah is to buy what is at the top of the date-palm trees in return for a certain number of Wasqs of dried dates.'"

"Ibn 'Umar used to take rent for some land, then he heard something from Rafi' bin Khadij. He took me by the hand and went off to Rafi', and I was with him. Rafi' narrated to him from some of his paternal uncles, that the Messenger of Allah forbade leasing land, so 'Abdullah stopped (doing that) afterward."
