What is the ruling on my remaining with my committed husband who smokes cigarettes, knowing that he is trying to quit and has gone through difficult circumstances?

Smoking is forbidden because it causes severe harm and is not a cure for psychological stress or difficult problems. The correct treatment is to turn to Allah and to utilize permissible means. It is advisable to conceal the fault of the husband who smokes, to advise him gently, to encourage him, and to be a support for him in quitting smoking.
