Praise be to Allah
One of the kinds of tests is that Allah may test one spouse with bad treatment on the part of the other, for whatever reason. Based on this, if what you have mentioned is correct and your husband has been bewitched or affected by strong hasad (envy) – for witchcraft and the evil eye do have an effect, as the Prophet (peace and blessings of Allah be upon him) said, “The evil eye is real” [al-Bukhaari, Muslim] – then you have to do the following:
1 – Remember Allah a great deal (dhikr) and pray for forgiveness. Ask Allah to heal your husband and to make him be as he used to be. Nothing can alter the divine decree except du’a.
2 – Think about yourself and the way you treat your husband. It may be that you have changed in the way you treat him, without realizing. Be the best wife you can to him, and the best help, after Allah. Stand by his side during this trial and be his support, after Allah.
3 – Do not go to so-called man of religion, for he is asking for your picture in order to practice trickery.
4 – There is nothing wrong with you going with your husband to a trustworthy shaykh, who treats people by means of the Quran and du’as prescribed by the Prophet (peace and blessings of Allah be upon him). You could also recite the Quran over some water and you and your husband drink from it, and you could recite ruqyah (incantation) over him every day, and recite Surah al-Baqarah in the house.
5 – Assuming that what has happened to your husband is not witchcraft or hasad (envy), then sit with him and discuss things frankly. Tell him what you feel, and agree to go back to the way things were.
6 – You can ask some people – especially trustworthy relatives - to intervene and seek a solution to this problem, and to look into its causes and try to find a way of resolving it.
Finally, we advise you to weigh up your husband’s good points and bad points, and do not forget his good qualities and his kind treatment of you, because this will motivate you to try to bring him back to the right path in his religion and in his relationship with his Lord, first of all, then in his relationship with you.
May Allah make things easy for you, and make your husband happy with your obedience and make you happy with his good treatment.
And Allah knows best.
