Is the husband entitled to request his wife's daily permission before she goes to work, even though she was employed before marriage? And is this considered an injustice to her and a diminishment of her rights?

A wife is not permitted to leave her husband's home without his permission, whether for work or any other reason. This right is not forfeited by her being employed before marriage, unless this was stipulated in the marriage contract. If she leaves without his permission, she is disobedient (ʿāṣiyah) and rebellious (nāshiz). It is advisable to handle the matter wisely by explaining the religious ruling to her and not preventing her from going out for a permissible job, unless there is a need, hardship, fear of temptation (fitna), or harm.
