A:
Ruqyah is permissible as long as it does not entail any Shirk (associating others with Allah in His Divinity or worship) or any illegal Du`a' (supplication).On the other hand, it is impermissible to use the books of "Al-Hisn Al-Hasin", "Hirz Al-Jawshan", or "Al-Sab` Al-`Uqud Al-Sulaymaniyyah" as incantations.At the same time, reciting Ayat-ul-Kursy when going to bed is beneficial. Similarly, the recitation of Surahs Al-Ikhlas and Al-Mu`awwidhatayn (Surahs Al-Falaq and Al-Nas) is useful.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
