لا يقال: لو كان الكفر بقضاء الله تعالى لوجب الرضا به
It should not be objected: if disbelief occurs by divine decree, approving it would become obligatory.
The objection can be presented as an argument:
1. Every occurrence falls under decree.
2. Acceptance of divine decree is required.
3. Therefore every occurrence, including disbelief, must be approved.
The conclusion shifts from decree as divine determination to the decreed act as an object of moral evaluation. Those are not identical subjects. The reply examines this hidden change in meaning rather than denying that disbelief can occur within divine decree.
