The ruling on stipulating a guarantee for a borrowed item if it is damaged

The Shaykh : However, if a guarantee is stipulated upon him, such that the lender says, “There is no harm; I am lending this to you, but on the condition that you guarantee it if it is damaged, whether you committed an excess or not,” and he commits to that, then he is liable for the guarantee. This is because he is the one who obligated himself to this. Therefore, the correct view is that it is not guaranteed unless the borrower commits to the guarantee.
