Faulty formulation: Once the right of intercession is established, the intercessor can independently alter divine judgment without Allah's permission.
Correct formulation: The Messenger's intercession is true, but it remains subject to Allah's permission and will. It is an avenue of divine mercy, not an independent divine power held by any creature.
Application: Intercession for the commencement of judgment and intercession on behalf of a sinner serve different purposes. In both, however, Allah alone remains the final Judge and source of authority.
