Abu Salama bin 'Abdur Rahman أبو سلمة بن عبد الرحمن بن عوف · The Book of Agriculture

"Whoever has land, let him cultivate it. If he is unable to cultivate it, let him give it to his Muslim brother and not share-crop it with him."

"Some people had some extra land which they leased out in return for half of the yield, or one-third, or one-quarter. The Messenger of Allah said: 'Whoever has land, let him cultivate it, or give it to his brother to cultivate or keep it (without cultivating it).'"

"The Messenger of Allah addressed us and said: 'Whoever has land, let him cultivate it or give it to someone else to cultivate, and let him not rent it out.'"

"One of them may cover for the other if they were partners."
