I asked Abu Ibrahim (Imam Musa ibn Jafar Al-Kadhim (as)) about a man who takes a slave as collateral (rahn), and the slave suffers an injury, such as losing an eye or any reduction in his physical condition. Who bears the loss for such a deficiency? Imam (as) replied: "It is upon his master." I said: "The people say that if you give a slave as collateral and he falls ill, loses an eye, or suffers a physical defect, the man's wealth should decrease in proportion to the loss in the slave." Imam (as) said: "What do you think, if the slave committed murder, who would bear the liability for his crime?" I replied: "His liability would remain upon him."
