ولا ربا بين المولى وعبده
Translation: In the stated historical framework, no riba is deemed to arise between a master and an enslaved person under the relevant conditions.
Quduri ends with a historical master–enslaved person rule formulated within classical legal assumptions about property ownership. Under some classical conditions, property held by an enslaved person was not treated as independently owned for this exchange analysis.
Hanafi commentaries expressly qualify the issue by trading authorization, creditors’ rights, and the status of a mukatab. This is historical jurisprudence and does not describe present-day employment or imply that one person may own another person today.
