Cursing the Wife and Its Expiation

Question:
The second one says that you were pleased, yes, and this is one of the wife's sons, so is this forbidden? And what is required of him?

Answer:
There is no doubt that this is forbidden. It is not permissible to curse your wife, nor to curse any of the Muslims. Even if it is regarding the medicine, the dwelling, or obedience, it is not permissible to curse them. Cursing is a vile word and an insolent word. Its ruling returns to the one who said it if the one it was directed at does not deserve it, so it returns to its owner, and the sin is upon him.
So it is not permissible for you to curse any of the Muslims, especially your wife, the mother of your children, and your relative. This is a matter that is not permissible for you. You must repent to Allah the Mighty and Majestic and not return to such a thing. As for the expiation, there is no expiation for it other than repentance and seeking reconciliation. Yes.
