إِذْ لَيْسَ كُلُّ مَا فِيهِ مَعْنَى الشَّيْءِ حُكْمُهُ حُكْمَ ذَلِكَ الشَّيْءِ
Not everything sharing a meaning must share the same grammatical ruling.
This principle is crucial when analyzing responses and connectors. An interrogative can convey rebuke, warning or invitation, but it does not necessarily inherit every grammatical rule belonging to the basic form of that intended meaning.
For example, rhetorical denial inside a question does not make its syntax identical to an explicit negative proposition. Grammatical judgments require attention to wording, governance, inflection and discourse evidence—not semantic resemblance alone.
