Abdur Rahman bin Mahdi عبد الرحمن بن مهدي · The Book of Agriculture

The Messenger of Allah said: "Whoever has land, let him cultivate it or give it to his brother, and not lease it to him."

"Two of my paternal uncles used to cultivate (land) in return for one-third or one-quarter of the crop, and my father was their partner. 'Alqamah and Al-Aswad knew about that and did not change anything."
