فتجويز تقديم المعنوي دون اللفظي تحكم
Allowing the semantic agent to be fronted while disallowing the grammatical agent is an arbitrary distinction unless justified.
The objection asks why fronting the bearer of the action in meaning should be permitted but fronting the verb's formal agent be rejected as a matter of fiat. The response must inspect the verb's pronominal link, the role of the nominal subject, and the relevant grammatical conventions.
Examples:
«قام زيد» — Zayd is the agent placed after the verb.
«زيد قام» — Zayd occurs first and the verbal clause may serve as his predicate.
This is a change in grammatical predication, not simply the exchange of two independent words.
