and others do not. Allah has made the revelation He made to His Prophet (peace be upon him) as good, guidance, and remedy for all sufferings including the physical and psychological diseases. This remedy is beneficial for the slaves and brings many good things that none but Allah knows their number. Man may experience certain conditions that cause him to fear without knowing the reason behind it. Allah makes His revelation through His Prophet (peace be upon him) good, safety, and a remedy for many sufferings that none but Allah knows their number.
I advise those two questioners to use the revelation of Allah to get safety, tranquility, peace, and protection from satanic tricks. Among these things is reciting AyatulKursy (the Qur'anic Verse of Allah's Chair, Surah AlBaqarah, 2:255) after each Prayer following the Dhikr (Remembrance of Allah). In this Ayah, Allah (Exalted be He) says, Allâh! Lâ ilâha illa Huwa (none has the right to be worshipped but He), AlHayyulQayyum (the Ever Living, the One Who sustains and protects all that exists). To the end of the Ayah.
This Ayah is the best and greatest Ayah in the Qur'an, for it stresses the principle of Tawhid and devotion to Allah (may He be Praised) and shows His sublimity and that He is the Ever Living, the Owner of everything and nothing weakens Him. When a man reads this Ayah after each Prayer and before going to bed, it protects him from every evil. The Prophet (peace be upon him) said that whoever recites it once before going to bed, there will be a guardian appointed over him from Allah who will protect him during the night and Satan will not be able to approach him until morning. The patient should try this proven prescription and he will not see any harmful thing as the Prophet (peace be upon him) did not tell anything except the truth.
