Question: I have a problem. I need to share it with you to get some solution of it. A girl is after my husband. She is making use of magic and spells to control him. My husband is least interested in her, but I don’t know with what magic tricks she is trying to get control of his mind. At times, my husband suffers from fits in which he does not recognize anyone, forgets his past, and starts thinking about her. I am extremely worried and so is my husband. Few days back, my husband had blood spots on the back of his shirt as well. Kindly suggest any type of tasbih (words praising the Lord). 

    Answer: I am sorry to hear that some woman is contriving to ruin your marital life. She is certainly incurring a grave sin and if she does not stop, she will meet a dreadful fate in the Hereafter and very likely in this world too.
    Two surahs from the Holy Qur’an namely Surah al-Falaq and Surah al-Nas would be helpful in this regard. Ask your husband to learn their meanings and recite them whenever he finds time in his day while pondering on the message both surahs communicate. You may please know that there is no strong and lasting shelter than the shelter of God from all that is evil. These surahs are in fact supplications; whoever utters these finds himself under the supreme protection of Allah. He feels that he is wreathed by the divine circle of a large squad of angels who protect him all the time as he seeks his Lord’s refuge. 
    In addition, you and your husband also need to establish your obligatory prayers five times a day. After saying your obligatory prayer, you should pray to the Lord for your husband. I believe no one can pray for him as sincerely as you—his wife—can do. 
    There are two other supplications of the Prophet (sws), which you and your husband may recite whenever be in distress. These are:

 حَسْبُنَا اللَّهُ وَنِعْمَ الْوَكِيلُ عَلَى اللَّهِ تَوَكَّلْنَا (تِرْمَذِى  رَقَم: 3355)

Allah is sufficient for us. He is the best disposer of affairs. In Allah [only] we repose trust. (Tirmidhi, No: 3355) 

إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ اللَّهُمَّ أْجُرْنِي فِي مُصِيبَتِي وَأَخْلِفْ لِي خَيْرًا (مُسْلِم رَقَم: 1565)

We belong to Allah and to Him shall we return; O Allah reward me for my affliction and give me something better in exchange for it. (Muslim, No: 1565)

    Spells often cause psychological effects, as you mentioned about your husband that he forgets things. I would very humbly suggest that if this woman is from among your relatives or in a position where you and your husband have to see her, you both should immediately rearrange your plans as to avoid even having a look at her. Your husband especially needs to never come in any sort of contact with her. Let her do, in his absence, what she pleases but ask your husband not to see her anyway. I am very hopeful this will greatly help.
