الكفر مقضي لا قضاء
Disbelief is something decreed, not decree itself.
Qaḍāʾ may denote the divine decision or attribute considered as decree; maqḍī denotes the event or act that occurs under that decree. Treating the two as one creates the false implication that every event must be loved or morally approved.
For example, a person's lie is within divine knowledge and decree as an event, but lying remains forbidden. Accepting divine wisdom is not equivalent to praising the lie. The distinction identifies two different objects of evaluation rather than merely substituting one word for another.
