Its form is used for many communicative purposes.
Use three steps: identify the imperative form, examine the speaker–audience relationship and context, and determine the intended rhetorical force. Without these steps, it is easy to mistake every imperative for a duty or every difficult request for taʿjīz.
A comparative reading helps: iʿmalū mā shiʾtum signals threat; faʾtū bi-sūrah is a challenge; kūnū qiradatan represents subjugation; kūnū ḥijāratan conveys humiliation; fa-ṣbirū aw lā taṣbirū equalizes alternatives; and rabbī ighfir lī is supplication. Each reading depends on its particular cues.
