Declarative and Performative Speech — Khabar and Insha'

Khabar (declarative): Speech admitting truth/falsehood — describes a reality.
Insha' (performative): Speech not admitting truth/falsehood — its utterance constitutes meaning (command, prohibition, question, wish, address).

Declarative form used for performative meaning in the Quran: "Divorced women shall wait by themselves for three periods" (2:228) — declarative form, obligatory command intended.

Rhetorical wisdom: Framing a command as a statement implies compliance is taken for granted — as if already happening, leaving no room for debate, making it more forcefully obligatory than an explicit command.
