Once the pledgor fully pays the secured debt, the basis for retaining the collateral is satisfied. The pledgee must release it.
For example, 700 of a 1,000-dirham debt was repaid earlier and the final 300 is now paid, leaving zero outstanding. Collateral held solely against that debt must no longer be retained on the basis of that pledge. Any independently established legal claim would require separate treatment.
