If the husband’s earnings are totally from unlawful sources, the woman should ask here husband to spend on her Halal (i.e. lawful) money or otherwise to give her divorce. If the husband does not accept any of the conditions, the wife must approach the Hakim-e-Sharh (i.e. the highest religious authority) to deal with her husband and if unavoidable, procure divorce for her. In the case where the husband has sinful tendencies and habits, the wife cannot refuse to honour his conjugal rights. She must hate the evil-habit and not her husband and try to reform him patiently.   _{Your Comment}
