Is it permissible for a woman to live with her husband, who works as a cashier in nightclubs where temptation and dancing are mixed, out of fear that his money may be unlawful?

If amusement parks are set up to provide a place for indecency and dancing, and for the unlawful mingling of men and women, then working in them is forbidden (haram (definition)). Any wages the husband earns from such work are ill-gotten gain (suht), and he must repent to Allah and cease this work immediately. As for the wife, it is not permissible for her to take from his money earned from his forbidden work, except out of necessity or need, and only to the extent of that necessity or need.
