When “dhālika al-kitāb” is understood to convey eminence or perfection, an objection may arise: how does an exclusion of doubt count as reinforcing the same claim? Removing a possible reservation strengthens precisely that earlier assertion.
However, if the initial words are parsed differently and do not form an independent clause, the faṣl analysis must be reconsidered on that grammatical basis. Syntactic alternatives and the rhetorical conclusion should not be silently conflated.
