Qatada قتادة · The Book of Agriculture

"Arable land used to be leased out at the time of the Messenger of Allah on condition that the owner of the land would have whatever grew on the banks of the streams and a share of straw, I do not know how much it was."

"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."
