What are the husband's rights over his wife, what is the ruling on the wife taking from his money to cover household expenses, and what is the ruling on her leaving the house if they are separated but living together, and the husband refuses to discuss matters of her going out or visiting?

If the divorce has not actually occurred, the wife must obey her husband in what is right and permissible, and she is not allowed to leave the house without his permission if he has paid her the prompt dower. It is the wife's right that her husband treat her kindly, safeguard her chastity, and provide for her financially. If he falls short in providing for her, she is entitled to take from his money what suffices her in a reasonable manner, without excess. However, if he has divorced her with a revocable divorce, she is entitled to maintenance and lodging. If the waiting period (iddah) has ended, she is irrevocably separated from him, and he no longer has any right over her.
