Is it permissible for a woman to seek divorce from her husband, who insists on selling pork in his restaurant despite her advice, and they are physically separated?

If the husband sells pork, it is a reprehensible and forbidden act, and he should be advised in the best manner. The wife's refraining from eating from his money, which is mixed with lawful and unlawful earnings, is good, but it is not unlawful. Separation does not mean divorce has occurred unless the husband pronounces it. It is permissible for the wife to request a divorce due to the husband's insistence on selling pork, because of his transgression, but it is not obligatory if she fears negative consequences, such as a detrimental effect on the children. In such a case, she should be patient with him and supplicate for his guidance. The wife is obligated to obey her husband in permissible matters as long as she is under his marital bond.
