What is the ruling on a wife remaining in her job outside the city despite her husband's demand for her to leave it and her falling short in his rights, and is he obligated to provide for her while she is working?

The basic principle is that a woman does not leave her husband's house without his permission. His knowledge of her working before marriage does not obligate him to give permission after marriage, unless she stipulated that condition in the marriage contract. If her work causes a neglect of the husband's rights and her home, he has the right to revoke this condition. The husband is obligated to financially support his wife, but if she leaves without his permission and without necessity, she is considered disobedient (nashiz) and loses her right to financial support. The husband may permit her to go out for lawful work on the condition that she gives him a portion of her salary.
