Sunan Ibn Majah
Hadith #2450
It was narrated that 'Amr bin Dinar said:βI heard Ibn 'Umar say: 'We used to lend land for cultivation in return for a share of the harvest, and we did not see anything wrong with that, until we heard Rafi' bin Khadij say: βThe Messenger of Allah (ο·Ί) forbade it.β Then we stopped because of what he said.' β
