What is the ruling if the statement is interpreted as a pledge (rahn) of the slave for one thousand?

Primary text

There are two views concerning the interpretation that the slave was pledged for one thousand. The first view holds that this explanation is not accepted because the right of the pledgee is against the debtor's personal liability (al-dhimma). The second view holds that it is accepted because the debt is attached to the pledged item, making this interpretation valid, similar to the case of a fine.
