قَدْ تَخْرُجُ صِيَغُ الأَمْرِ عَنْ مَعْنَاهَا الأَصْلِيِّ إِلَى مَعَانٍ أُخَرَ، تُفْهَمُ مِنْ سِيَاقِ الْكَلَامِ وَقَرَائِنِ الأَحْوَالِ
Imperative forms can depart from their primary meaning into other meanings understood from verbal context and situational clues.
Verbal context includes surrounding expressions, what the listener knows and the discourse objective. Situational clues include the relation between speaker and hearer and what is happening at the time.
For example, “أَعْطِنِي” addressed to an equal may be a request (iltimās), while “رَبِّ أَوْزِعْنِي” directed to God is prayer (duʿāʾ). The grammatical shape is imperative in both, but the intended rhetorical act differs.
