Is a wife considered sinful if she leaves the marital home due to her husband's mistreatment of her, his forcing her to work, and his indifference towards her, especially after she becomes pregnant?

The wife has the right to housing and maintenance. It is not permissible for the husband to obligate his wife to pay rent, or to spend on herself, or to work if she does not wish to do so. The wife should advise her husband and remind him of good companionship, and frequently supplicate for him. If the situation persists, the wife has the right to seek divorce. If he does not respond, she should refer the matter to the competent authorities. There should be no haste in seeking divorce, especially if the wife has no family in the country. It is permissible for the wife to leave her husband's house without his permission if he does not provide for her, but this is not advisable if she has no shelter or fears danger for herself.
