The ruling on believing that the saliva of some people contains healing and going to them

Question:
May Allah reward you. The questioner, Abu Mu'adh from northern Sinai, Egypt, says: Some people go to those who claim to be awliya (close friends of Allah) and lie on the place of the pain, claiming that this person's saliva is blessed and contains healing. What is the ruling on going to these people? If these people are righteous in their creed and upright, and one goes to them for the Shari'ah-prescribed ruqyah (healing by Qur'anic recitation), if these awliya are righteous in their creed and upright in their religion, the sick or injured person goes to them for the Shari'ah-prescribed ruqyah so that he recites and blows.

Answer:
From his saliva, there is no harm in that. The Shari'ah-prescribed ruqyah is permissible, and it is a form of treatment and healing by the permission of Allah. However, if these people who are called awliya are corrupt in their creed, calling upon other than Allah, or seeking aid from the dead, or performing acts of disbelief and shirk (associating partners with Allah), then it is not permissible to go to them. This is not ruqyah; this is kufr (disbelief).
