What is the ruling of Islamic law on the marriage of a man who concealed his smoking from the wife's family, given that she requested divorce after finding out, and is the marriage contract considered void or invalid?

Smoking is forbidden, and its harms are proven. It is not permissible for the suitor to conceal the fact that he smokes if he knows that the woman would not accept him with that habit, for this is deception, and "whoever deceives us is not of us." If deception occurs, the deceiver has committed a sin and must repent. However, this does not affect the validity of the marriage, and the wife does not have the right to annul the marriage. We advise the husband to abandon this habit and the wife to help him. If he does not quit and she is harmed, then she has the right to seek a divorce due to harm.
