If a man has money and his wife is in need of it, and it is obligatory for him to give it to her, is it permissible for her to take it without his knowledge?

Question:
Is it permissible to take money from the husband when it is in front of him, after asking him for it and he refuses to give it, even though he is the one who has the money? Is it permissible to take it in that case or not? We have heard from one of the honorable scholars that it is permissible to take it to the extent of the need. May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad. To proceed: Allah, Glorified and Exalted is He, has made the maintenance of the wife and the maintenance of children who do not earn a living obligatory upon their father and upon their husbands.
So if the husband fulfills the obligation, or the father fulfills the obligation toward his children by spending on them what suffices them in food, drink, clothing, and shelter, then it is not permissible to take from his money. But if there is negligence in the maintenance that is obligatory upon him, and his wife gets hold of his money, she has the right to take what suffices her and her children.
In a proper manner. Is extravagance allowed? Because of the saying of the Messenger (peace and blessings be upon him) when Hind was fasting. Yes. In the case where it was reported, may Allah be pleased with her, that her husband Abu Sufyan, may Allah be pleased with him, was a stingy man who did not give her what sufficed her and her child, so the Messenger (peace and blessings be upon him) said to her: Take what suffices you and your child in a proper manner.
