Shaykh Bin Baz was asked:
Much of what I suffer from is the sickness of Jaathoom (sleep paralysis) and I have heard many people many times mention that they suffer from this sickness. So what is the origin of this sickness? Is it a bodily sickness or is it psychological or is it from jinn? What is the way to dispose of it?
“On this issue I don’t know of anything clear except that I advise to practice the legislated (supplications) for seeking refugee when going to sleep. A person, if he comes with the legislated Dhikr when going to sleep, الله لا إله إلا هو الحي القيوم … (Ayah-tul Kursi) and he reads قل هو الله أحد and the Mu’awadhatain (surah Falq and surah Nas) three times when going to sleep, he will be safe from this inshallah. And from this he says:
أعوذ بكلمات الله التامات من شر ما خلق
three times when going to sleep and in the beginning of the night and
بسم الله الذي لا يضر مع اسمه شيء في الأرض ولا في السماء وهو السميع العليم
three times in the beginning of the night and when going to sleep. All of this is protection from the ways of protection against this Jaathoom. Most times, and Allah knows best, it is from the action of Shayateen. However, these remembrances and supplications of refugee remove it and prevent it. All praise is due to Allah.
Our sister mentions, generous Shaikh, that she is consistent upon the remembrances of the morning and evening?
When she is truthful this evil will remove. When she is truthful in that and comes with it upon knowledge, certainty and Ikhlaas (sincerity), then Allah will shield her from this evil.” End quote. [Reference]
