All perfect praise be to Allah, The Lord of The Worlds, and may His Peace and Blessings be upon our Prophet Muhammad and upon all of his family and companions.

The basic task for a woman is caring for children and upbringing them according to Sharia to create a virtuous and God-fearing generation.

If necessary, it is permissible for a woman to go out for work under the following conditions:

First: The work suits her physical and psychological nature and her field of specialty.

Second:  She doesn`t stay in private with non-Mahrams.

Third: She doesn`t intermingle with the opposite sex.

Fourth: She observes decency and the Islamic dress code.

Accordingly, it is impermissible for a woman to go out for work without the permission of the husband ; but doing otherwise will render her disobedient to Allah, recalcitrant, and not entitled to any provision from her husband.

However, even if the husband approves of her going out for work, he is allowed to change his mind later on and she must respect his decision because spouses` rights are mutual. In other words, a husband is obliged to provide for his wife and she is to remain in the house in fulfillment of his rights over her. 

Therefore, if having a job for her is stipulated in spouses' marriage contract, but he bans her from that to inflict harm upon her, then she should go to a Sharia Judge. And Allah The Almighty Knows Best.
