أَمَّا النَّتِيجَةُ فَوَاحِدَةٌ.
As for the conclusion, it is one and the same.
“Ammā” isolates a second aspect of the discussion: wording may vary while the result of the inquiry remains consistent. “Al-natījatu” is the subject and “wāḥidatun” its predicate; the fāʾ marks the response required by “ammā.” It should not be treated as having precisely the same consecutive force as the fāʾ in “rājaʿnā ... fa-wajadnā.”
The comparison therefore keeps two claims distinct: textual difference and agreement in conclusion can coexist. Such careful partition accepts the objection within its proper scope without surrendering a claim that the objection has not actually defeated.
