إِيَّاكَ نَعْبُدُ
You alone we worship.
The unmarked order could be naʿbuduka, placing the object after the verb. Here the object is preposed, giving a focus of exclusivity: worship is directed to Allah alone. This is a clear instance in which word order carries rhetorical force.
Preposing need not signal exclusivity in every construction; it can mark emphasis, thematic prominence or other functions. Here the devotional meaning supplies strong contextual support for a restrictive reading.
