What is the ruling on saying "May Allah disfigure your face" to one's wife? And is this ruling the same as saying it to others, or to disbelievers?

The Prophet, peace and blessings be upon him, forbade saying "May Allah disfigure his face" and "Do not disfigure the face." The reason for this prohibition is that Allah Almighty created Adam in His image, and the face is honored. This prohibition is general, encompassing all human beings, including both disbelievers and Muslims. Disfiguring the wife's face falls under this prohibition, and the Prophet, peace and blessings be upon him, specifically mentioned her in this ruling as a warning against being lenient with the forbidden speech.
