What should a wife do with her husband who does not fast or pray, prevents her from doing good, and monitors her with suspicion?

It is not permissible for a Muslim woman to remain with an unbelieving husband who abandons prayer, as the marriage between them is null and void unless the husband repents and returns to Islam. This behavior of the husband may be due to the illness of doubt and obsessive thoughts, which can only be removed by the remembrance of Allah and seeking refuge in Him. The husband is advised to return to his religion and to seek refuge in Allah from Satan, the accursed, and to be diligent in reciting supplications (dhikr) to ward off obsessive thoughts.
