To identify a rhetorical effect, first establish the exact Arabic wording and grammatical role, then determine whether the clause is an assertion or a speech act, relate it to its neighbors, and finally explain the effect achieved by that construction. A marker and its rhetorical consequence are not the same thing.
Lā aʿbudu — a negated verb, not a prohibitive jussive.
Yadkhulūn — an imperfect verb; here commonly analyzed as a circumstantial clause.
Fa-sabbiḥ — an imperative whose fāʾ links back to the temporal-conditional frame.
This sequence prevents overconfident claims about repetition, fronting, coordination, and concision.
