أعتق عبدك عني بألف درهم
Emancipate your slave on my behalf in return for a thousand dirhams.
This historical jurisprudential example concerns ownership and acting on another person’s behalf. For manumission to be attributed to the requester in the envisaged manner, an appropriate proprietary relationship is required first.
When the price “a thousand dirhams” is specified, a transfer by sale is taken as the necessary implied transaction before the requested manumission can operate. A legal premise is supplied because the stated result depends on it.
The example belongs to a historical legal system of slavery; it does not endorse present-day trading in persons. Its teaching purpose is the structure of a legally necessary implication.
