Is it permissible for a man to beat his wife if she verbally abuses him?

A wife who verbally abuses her husband commits a sin, and the husband has the right to discipline her. This is not considered nushuz (rebellion) in a way that she would be treated as a rebellious wife. The husband may discipline his wife himself in cases of insults or foul language, and he is not required to refer the matter to a judge, provided that he believes beating will be effective, and on the condition that it is not severe, not on the face, and not on vital areas.
