In “sa-aqḍī ḥājatī thumma attaqī ʿaduwwī,” thumma establishes the sequence: strike first, secure oneself afterward. Both main verbs are first-person singular imperfects; the first also bears the future prefix sa-.
Min warāʾī locates the force behind the speaker, while muljam evokes horses already bridled for action. The syntax conveys deliberation rather than a sudden, unplanned outburst.
