Is it permissible to request a divorce and remove the hijab in order to work and provide for the children, due to the wife's fear of committing an act of disbelief as a result of her husband's abuse because she is unable to work while wearing the hijab?

Faith is not so trivial that it can be exchanged for disbelief at the slightest trial; prophets and righteous people endured the severest of trials. This world is a place of trial, and a trial can be good for a believer if they are patient and grateful. One must seek refuge from the whispers of disbelief and repel them. A woman is not obligated to work to provide for herself; rather, her maintenance and that of her child are obligatory upon her husband. It is permissible for her to take money from him if he refuses to provide, or to refer the matter to the court. The hijab is an obligation that may not be removed except out of necessity, to the extent and for the time required, and it ceases to be permissible once the necessity is gone. Necessity is when a person reaches a point where they fear perishing or facing unbearable hardship. It is permissible for a woman to seek divorce due to clear harm, and obedience to parents is not obligatory if they command her to refrain from something while she is suffering harm. It is best to consult scholars or Islamic centers to clarify matters and resolve the issue.
