Does the wife bear sin if her husband, a barber who shaves beards, mustaches, and heads, spends on her, knowing that part of his money is permissible (shaving heads and mustaches) and part is forbidden (shaving beards and fashionable hairstyles), and given that she is gradually advising him about the impermissibility of shaving the beard?

We ask Allah to reward you for your eagerness to distinguish between what is lawful and what is unlawful. We have previously clarified the conditions for the permissibility of opening a barbershop for men in previous fatwas. We also explained the permissibility of eating from mixed wealth, while emphasizing the importance of abstaining from it out of caution. Therefore, if you are able to spend from money that is not mixed with lawful and unlawful wealth, that would be better. However, if that is not possible, then there is no harm in spending from your husband's money. You should advise your husband to adhere to the rulings of Islamic law in his work.
