Ruling 2368

If a person is neither negligent in safeguarding the loaned property nor excessive in using it, but it so happens that the property perishes, he is not responsible (ḍāmin) for it. However, if a condition is stipulated that in the event that the property perishes the borrower will be responsible for it, or if the loaned item is gold or silver, the property must be replaced.
