مَا تَعْبُدُونَ ... مَا أَعْبُدُ
What you worship ... what I worship. (109:2–3)
One established analysis takes mā as relative, focusing on the object of worship. Some grammatical and exegetical discussions also entertain a maṣdariyyah reading, which can foreground the act or mode of worship.
These discussions do not obscure the core message: the two parties do not share the worship being proposed. A responsible analysis distinguishes a well-supported interpretation from a claimed unanimous grammatical ruling.
