What is the required repayment for a fungible item (mithli) loaned?
Chapter on Loan (Qard)
Al-Mughni
Book of Sales
Primary text
The borrower must return the equivalent amount (the like) of the fungible item loaned, regardless of whether its price has increased or decreased, or if it is still in its original condition. If the exact item loaned still exists without any defect, its return must be accepted, irrespective of price changes. If a defect occurs in the loaned item, its acceptance is not mandatory.
