ومن حكمه: أنه يستغني عن النية
A characteristic of explicit language is that it does not depend on a separate intention selecting its meaning.
When an expression directly and conventionally denotes a legal act, there is no need for an additional indication choosing that same meaning from competing senses. The expression itself carries the necessary clarity.
This is a rule about operative explicit statements in their appropriate setting, not a claim that every stray sound or irrelevant utterance automatically produces a legal effect.
