وَأَمَّا بِنِعْمَةِ رَبِّكَ فَحَدِّثْ
And as for your Lord’s blessing, proclaim it. (الضحى: 11)
Unlike the two preceding units with accusative nouns, this third member fronts the prepositional phrase bi-niʿmati rabbika. Fa-ḥaddith is an imperative: the blessing is made the stated topic before the instruction to speak of it.
Fronting should not automatically be equated with absolute exclusivity; its full force depends on context. What is clear is the structured threefold division: the orphan, the petitioner and the divine blessing each receive a corresponding directive related to the prior favors.
