The central conclusion is that an addressee’s apparent category and the category adopted in rhetorical address can differ for sound contextual reasons.
1. A non-questioner can be treated as questioning when prior hints create anticipation.
2. A non-denier can be treated as denying when the circumstances suggest resistance.
3. A denier can be treated as non-denying when compelling evidence is available.
The analysis of «لَا رَيْبَ فِيهِ» further distinguishes treating doubt as null from omitting emphasis to a denier. Negative reports, like affirmative ones, also follow the initial, hesitant, and denial-sensitive patterns.
The next section, al-isnād al-ḥaqīqī (literal predication), shifts from audience-sensitive wording to the nature of the ascribed relation.
