All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
We advise the woman in question and others to fortify themselves against the devils and their evil through saying the morning and evening Athkaar (mentionings and remembrances of Allaah) regularly, maintaining a state of ritual purification, ignoring the whispers of Satan and knowing that he is an enemy who does his utmost to harm humans in any possible way. It is proven in the Sharee‘ah that the devils assault humans through becoming partners with men in their wives. Allaah The Almighty Says (what means): {And incite [to senselessness] whoever you can among them with your voice and assault them with your horses and foot soldiers and become a partner in their wealth and their children and promise them. But Satan does not promise them except delusion.}[Quran 17:64]
The partnership of the devil with man in his children was interpreted to mean that he wraps himself around the penis of the man who has sexual intercourse without first seeking refuge with Allaah The Almighty from the accursed Satan. Mujaahid mentioned that the Prophet, sallallaahu ‘alayhi wa sallam, ordered anyone who is about to have sexual intercourse with his wife to say “Bismillaah. Allaahumma jannibna ash-Shaytaan wa jannib Ash-Shaytaan ma razaqtana, (In the name of Allaah. O Allaah protect us from Satan and protect from Satan (our offspring) whom You will grant us.” If Allaah decrees that they will have a child, Satan will never harm him. [Al-Bukhari and Muslim] Once, a man told Ibn ‘Abbaas that his wife woke up and found a flame of fire in her vagina. Ibn ‘Abbaas told him that this happened because of sexual intercourse with a jinni.
And Allaah Knows best.
