Hammad bin Zayd حماد بن زيد بن درهم الأزدي الأزرق · The Chapters on Pawning

“I heard Jabir bin 'Abdullah say: Some men among us had extra land which they would rent out for one third or one quarter (of the crop). The Prophet (ﷺ) said: “Whoever has extra land, let him cultivate it (himself) or let him give it to his brother (for free, to cultivate it), and if he does not want to do that, let him keep his land.”
