«النهي عن الشيء يقتضي صفة القبح للمنهي عنه، إذا كان الناهي حكيماً»
A wise prohibitor’s ban indicates the badness of the forbidden act.
«إما أن يكون قبيحاً لعينه وضعاً أو شرعاً»
The act may be bad in itself, by its nature or legal classification.
«أو لغيره وصفاً أو مجاوراً»
Or it may be bad through an added quality or associated circumstance.
This distinction prevents treating every prohibition as the same kind of legal defect. Some acts are wrong at their core; others retain a potentially lawful basic form but become forbidden through an accompanying feature.
