وفي الشرع: تصرّف إلزام الفعل على الغير.
In legal usage, a command is an authoritative act imposing performance upon another.
Taṣarruf refers to an effective exercise of authority, not just uttering a sentence. Ilzām al-fiʿl is imposing a duty to act; ʿalā al-ghayr identifies another person as its addressee.
A binding sacred command is not merely a recommendation. Yet two people may both say “do this” while only one has the authority relevant to a legal obligation. Identical verbal forms do not guarantee identical legal consequences.
The definition foregrounds the authoritative nature of a legal command. Contextual uses and the different implications of the imperative form must still be distinguished.
