إِيَّاكَ نَعْبُدُ وَإِيَّاكَ نَسْتَعِينُ
You alone we worship, and You alone we ask for help.
The object pronoun إِيَّاكَ stands before the two verbs. In the context of devotion and monotheism, this conveys exclusivity of worship and appeal for help to God.
The construction identifies to whom the acts are directed. Its strong restrictive force follows from the expression together with its religious and discursive context; other instances of fronting still require separate analysis.
