An imperative may express subjection to an enacted outcome (التسخير), humiliation (الإهانة), or equivalence (التسوية) of alternatives. These differ sharply from an ordinary instruction the addressee is free to execute.
«كُونُوا قِرَدَةً خَاسِئِينَ»
Become despised apes.
The expression is not an ordinary practicable instruction addressed to a person.
«فَاصْبِرُوا أَوْ لَا تَصْبِرُوا»
Whether you endure patiently or do not endure patiently.
Here the two apparent options make no difference to the stated result. Identifying such usage requires preserving the distinction between the grammatical imperative and the actual intended force.
