A superficial declarative–imperative contrast cannot settle coordination on its own. Wording that looks like a report may serve a request or supplication in meaning; where both expressions have the same communicative function, coordination can be coherent.
غَفَرَ اللَّهُ لَكَ وَرَحِمَكَ.
May Allah forgive you and have mercy on you.
Both verbs have past morphology, but in a setting of prayer they are not reports that forgiveness and mercy occurred in the past. Their supplicatory purpose explains the semantic alignment. Rhetorical editing must consider intended force as well as form.
