Hadith.4116 - Fadalah narrated from Aban, from Abu Abdillah (as): "If two parties disagree about the value of collateral (rahn), with one claiming it was pledged for one thousand dirhams and the other claiming it was pledged for one hundred dirhams, the one claiming the higher value must present evidence. If he cannot provide evidence, the one claiming the lower value must take an oath." "Similarly, if the collateral is worth either less or more than the claimed amount, and they disagree about its status, whether it is collateral (rahn) or a deposit (wadi'ah), the one claiming it is a deposit must present evidence. If he cannot provide evidence, the one claiming it is collateral must take an oath."

Hadith.4117 - Safwan ibn Yahya narrated from Ishaq ibn Ammar, who said: "I asked Abu Ibrahim (Imam Musa ibn Jafar Al-Kadhim (as)) about a man who pledges a slave, garment, jewelry, or household items as collateral, and the owner of the property tells the creditor, 'You are permitted to use this garment, wear it, benefit from the property, and use the servant.' The Imam (as) replied: 'It is lawful for him if the owner permits it, but I do not like him to do so.' " I then asked: 'What if someone pledges a house that produces income, who does the income belong to?' Imam (as) replied: 'The income belongs to the owner of the house.' " I further asked: 'What if someone pledges a barren land and the owner of the land tells him to cultivate it for himself?' Imam (as) replied: 'This is lawful. It is not the same as the previous case. He cultivates it with his own money, so it is lawful for him as the owner has permitted it, because he invests his own resources and develops the land.' "
