What is the reason for the recurrence of nightmares involving jinn and demons, despite reciting the prescribed adhkar (remembrances) and Quran before sleep, and are they a result of envy (hasad) and sorcery (sihr), or do they have another implication?

We advise you to fear Allah, maintain ritual purity, perform the obligatory duties, shun sins, renew repentance, supplicate persistently, and regularly recite the Quran and the prescribed remembrances (adhkar). Trust in Allah Almighty that what you are experiencing will dissipate. Indeed, a believer is tested. What has afflicted you may be sorcery (sihr), the evil eye (ayn), a physical illness, or a psychological one. Therefore, we advise you to consult doctors and those who practice Ruqyah (definition) Shariah (Islamic exorcism/healing).
