Abu Ja‘far (a.s.), has said that ’Amir al-Mu’minin has said, ‘If one holds a piece of barren land as al-Rahn (security deposit) which has no fruits and he farms it and incurs expenses on it, he keeps accounts of whatever he has spent and his work; then counts the share of the land to compensate for his assets with which he holds the land as al-Rahn (security deposit) until he compensates his assets, then returns the land to its owner.’”
