هُوَ اللَّهُ أَحَدٌ
He is Allah, uniquely One. (112:1)
One recognized parse treats huwa as the subject, Allāh as its predicate, and aḥad as a second predicate. Another understands huwa as a pronoun of the matter (ḍamīr al-shaʾn), with 'Allāhu aḥad' functioning as the explanatory sentence. Both affirm divine oneness, although they assign different syntactic roles to the pronoun.
Under the pronoun-of-matter reading, the following clause unfolds a matter of special importance; the alternative emphasizes direct predication. One should not conceal the grammatical alternatives.
