Asslamu Aliakum,
If a wife continues to answer her husband back in a rude and inappropriate way, he may use physical force. I think by mouthy, you mean someone who is rude.
Yes, if a husband beats his wife, she can get a divorce. However, if she played a role in making her husband angry, then should she not do something to avoid angering people? For example, let's assume the wife was being rude to her husband on a regular basis. He snapped and hit her. In this case, the husband should not have lost her temper. The wife should not have been rude. So in this case, it's both are to blame.
Personally if I married a women who was rude/mouthy to me on a regular basis, I would divorce her and she can find another husband. The divorce will not have a significant impact on me, as I can always find another Muslim women.
I am clearly not talking about a slap across th face. People snap, that is understandable. But to beat someone black and blue? And to do it on regularly basis? No, the person who beat another human being is entirely to blame! Repeated slaps, punching and kicking is completely wrong. The prophet (pbuh) and huge argument and never has he or his companions beat their wives black and blue. There other avenue walk away and get divorce. Cosmic clearly is talking about women that are beaten. As if they don't blame themselves already she telling them to look their own behaviour rather seeking justice. If someone was beaten in the street, would we tell them to look their own behaviour or would we advise them to report it to the police?
I was looking for Islamic site I went to last year and I can't find it. A man posted and ask the scholar to help me. He punched his second wife in the stomach (once), she was pregnant after an argument. He blamed on his first wife ( for stressing out and apparently cursed him), black magic and his second wife.
You know how the scholar responded? He called his actions disgraceful for three reasons:
She was woman
She was his wife.
She was pregnant with his child.
Now, the rules are quick simple. There is no excuse to beating another human being. We are not even allowed to beat animals let alone a human. Victims ( man, woman, children, parents ) for violence in their own homes always blame themselves. There is a line, beating someone can kill them. So why would you cross that line? Especially if you can walk away? You cross it, you need to be punished! Simple
