Does divorce take place by saying "you are divorced" to the wife with the intention of frightening her and breaking her pride, while the husband is aware of her family's interference in their problems?

Your statement to your wife, "You are divorced," is an explicit pronouncement, and divorce takes effect thereby, without its occurrence being dependent on the intention to effect it. So, if you said that while being aware of what you were saying, your divorce has taken effect.

If you have not previously divorced your wife more than once, you may reconcile with her during her waiting period (iddah) without the need for a new contract or her consent.

Know that rectifying and disciplining a woman is not achieved by threatening divorce, but rather through the legally prescribed means.
