Does the husband have the right to reclaim the dowry if he divorces his wife who is ill-tempered, a smoker, does not pray, and spends her nights in chalets and resorts, especially if he only slept with her once and she used to refuse him?

Not every defect invalidates the marriage; rather, there are specific defects. And whoever accepts a defect after becoming aware of it does not retain the option to annul the marriage. A wife's refusal of the marital bed is an act of defiance (nushooz). This woman has combined neglecting her husband's rights through defiance, neglecting God's rights by abandoning prayer, smoking, and staying up late in chalets. Her separation is more appropriate. One should be deliberate in choosing a righteous wife.
