Musnad Ahmad 2085

It was narrated that ‘Amr bin Deenar said: I heard Ibn 'Umar say: We used to lease land in return for a share of the crop (mukhabarah), and we did not see anything wrong with that, until Rafi’ bin Khadeej said that the Messenger of Allah (ﷺ) had forbidden that. 'Amr said: I mentioned that to Tawoos and Tawoos said: Ibn 'Abbas said: Rather the Messenger of Allah (ﷺ) said was: "For one of you to give land to his brother is better for him than if he were to take a set amount (of the produce) in rent for it."
