وَمَا مُحَمَّدٌ إِلَّا رَسُولٌ
Muhammad is no more than a messenger.
Here “mā” is negation, “Muḥammadun” the subject, “illā” the exception marker, and “rasūlun” the predicate. The combined construction makes clear that the Prophet ﷺ, being a messenger, is not exempt from human mortality.
Incorrect inference: all virtues or other attributes of the Prophet are denied.
Correct inference: the statement emphasizes his actual status in the particular context of mortality. It is a key example of reading relative restriction within its purpose.
