Is a specification of debt accepted if the item has no customary monetary value?

Primary text

If the declarant specifies something that does not customarily hold monetary value, such as a nutshell or an eggplant peel, the admission is not accepted, because an admission signifies an established right in one's liability (*dhimma*), and such items cannot be established in liability. Similarly, if the specification is something not considered property under Sharia, such as wine, pork, or carrion, the admission is not accepted. The same applies if the debt is specified as a dog whose keeping is unlawful. If specified as a dog whose keeping is lawful, or as undressed hide of a dead animal, there are two views: the first accepts it, because it is something that must be returned and handed over, so the obligation covers it. The second rejects it, because admission is a report of what necessitates a guarantee (*ḍamān*), and these items do not necessitate a guarantee.
