إِيَّاكَ نَعْبُدُ
You alone we worship.
An adequate analysis states that iyyāka is an object placed before the verb and that the construction foregrounds worship directed exclusively to God. Merely saying “qasr” names the result without explaining why that label applies.
An unsupported excess would identify a specific historical opponent as the only target of this restriction without contextual evidence. A well-grounded answer gives the form, function and limit of the inference.
