والقضاء عبارة عن تسليم مثل الواجب إلى مستحقه
Qaḍāʾ means delivering an equivalent of the obligation to its rightful recipient.
The key expression is mithl al-wājib, a legally recognized equivalent of what was initially due. If the original act or object cannot be supplied, the law may direct the debtor or wrongdoer to a substitute.
For instance, if fungible property taken without right is destroyed, replacement by its equivalent becomes relevant. With nonfungible property, value may be due. Whether this substitute counts as complete or deficient qaḍāʾ is a distinct question.
