Is it permissible to marry a man who drinks alcohol, smokes, and is negligent in prayer, but is dutiful to his mother and treats others well, with the intention of changing him for the better?

This answer addresses three messages: to the guardians, to the suitor, and to the fiancée. It directs the guardians to find a suitable husband for their sister, one who possesses the qualities of religiousness and good character. They must not marry their sister to an infidel or an evildoer. As for the message directed to the suitor, it urges him to repent and return to performing prayer as Allah Almighty commanded, and to abandon other sins such as drinking alcohol and smoking. It also emphasizes the importance of his actions being righteous and upright to qualify him as a good husband. As for the fiancée, she is advised to be patient and steadfast in truth, and not to compromise on character and religiousness in choosing a husband. It states that a happy marital life is built upon religiousness and good character, and she should not accept anyone who neglects prayer or drinks alcohol.
