What is the ruling on saying "divorce is forbidden" if it slips from the tongue unintentionally, without intending divorce or having the intention of it?

If a husband utters the phrase "haram talaq" (unlawful, divorcing) unintentionally, as a slip of the tongue, then divorce does not occur, because intention is a pillar for its occurrence. What is considered is the intention behind the utterance and its meaning. The ruling is lifted for error, forgetfulness, slips of the tongue, and what the servant does not intend.
