All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad
is His slave and Messenger.
The husband has the right to prevent his wife from working outside the home, even if she wants to work to support her parents. Thus, it is not permissible for her to go out without his permission. If a woman marries, her husband has more right over her than her parents, and her obedience to him takes precedence over her obedience to her parents if it is impossible to combine both of them.
Furthermore, the husband is not obligated to support his wife’s parents financially unless he does so out of his own goodwill.
Lastly, if the parents are in need, their financial support becomes obligatory on their solvent relatives who are supposed to inherit from them, according to the most preponderant opinion of the scholars.
Allah knows best.
