Does divorce take place with the utterance, "You are of no obligation to me," if the speaker is unaware of the existence of divorce allusions (kinayat al-talaq) and did not intend divorce by it?

Divorce is not established solely by an explicit utterance; it can also be established by an implicit expression (kinayah), which is any word that indicates separation, such as "You are no longer bound to me." However, an implicit expression does not result in divorce unless there is an intention to dissolve the marital bond. Therefore, your statement "You are no longer bound to me" does not obligate you to a divorce due to the absence of an intention for divorce. It is advisable to avoid divorce-related expressions in the future due to the potential consequences they may entail.
