Is it permissible for a wife to refuse to engage in sexual relations with her husband and to decline sitting next to him at night due to his smoking, even though she was aware of this before marriage?

A wife must obey her husband in cohabitation with fairness and respond to his request for intimacy; otherwise, she exposes herself to the curse of the angels. However, if the wife is bothered by the smell of her husband's smoke, she is permitted to refuse until he removes the smell, because anything that harms a person, the husband must remove. The husband must quit smoking due to its harm to himself, his wealth, and his family.
