Can a devout believer be afflicted with madness? Does a person's madness indicate weakness in their faith? What are the detailed steps for self-exorcism (Ruqyah Shariah) for self-treatment without needing to go to a Sheikh?

It is advisable to rely on Allah, to have a good opinion of Him, and to be content with His decree. It is also recommended to be patient in the face of affliction, seeking reward, and to strive in supplication (Du'a) and legal Ruqyah (exorcism) using the Quran and established prophetic invocations. One should beware of sorcerers and charlatans. It is also recommended to consult a trusted psychiatrist for treatment, in compliance with the Prophet's (peace be upon him) command to seek medical treatment.
