Is a wife sinful if she refuses to stay in the marital home and moves to her family's house while her husband is traveling abroad for work, and is the husband obligated to provide for her in this situation, given that she is employed and has a monthly salary?

If a woman knows that her husband is displeased with her residing in her family's home, then she must obey him and remain in his house, and not leave except with his permission. If she leaves without his permission or refuses to stay in his house without a valid reason, then she is disobedient (nashiz) and has no right to maintenance until she returns, unless she is pregnant, based on the Almighty's saying: (And if they are pregnant, then spend on them until they deliver their burden). However, if her leaving the marital home is due to harm inflicted upon her, then she is excused legally and is entitled to maintenance. The fact that a woman has an income does not affect the obligation of her husband to provide for her maintenance.
