Is it permissible for me to ask for a divorce from my husband because he does not care about consuming haram (forbidden) and does not care about the future of the children? He is a father to seven children under the age of maturity, earning part of his income from renting out hookahs (smoking) in a place that is a park with mixing, music, and birthday parties. When I tell him that this income is haram, he gets angry and says: 'What remains in my house if you accuse me of feeding you and your children with haram?' My family's situation is unbearable, and I have a child with diabetes and a daughter with Down syndrome. He swears that he will prevent me from seeing my children if I divorce him. What do you advise me?
