What should a wife do regarding her husband who engages in forbidden relationships and obscene talk online and does not pray, knowing that he is kind and generous in his family life?

The reprehensible matters mentioned about the husband, such as engaging in illicit relationships, speaking obscenely to girls, and sending them indecent pictures, are even more reprehensible than his abandonment of prayer. This is because prayer is the connection between a servant and his Lord, and whoever neglects it is even more negligent of other things. Some scholars have even gone so far as to consider one who abandons prayer out of negligence to be a disbeliever. Therefore, it is necessary to continue advising him kindly, especially regarding prayer, and to seek assistance from righteous people and those close to him to remind him of it and the obligation of repentance, for prayer prohibits immorality and wrongdoing. The wife should also adorn herself for her husband and supplicate for him frequently, hoping that Allah will mend his condition.
