A command (amr) is a form that demands an act. In Hanafi legal theory, the default force of an unqualified command and the number of occasions on which an act is due are distinct questions.
Repeated daily prayers do not arise merely because the command form is linguistically repeated. Renewed prayer times also function as recurring causes of obligation.
Separate determinations
1. Is the expression a command rather than a report?
2. Does it indicate obligation or is there a modifying indication?
3. Is a single performance sufficient, or does a renewed cause trigger another duty?
The form of the command, the operative cause and the act's nature must be assessed independently.
