What is the ruling on going to the graves of the awliya (close friends of Allah) for a person to make du'a' (supplication) for himself, but next to the grave, because that is a righteous wali (close friend of Allah)?

Question:
Honorable Shaykh, may Allah grant you success. He says: What is the ruling on going to the graves of the awliya (close friends of Allah) for a person to make du'a' (supplication) for himself, but next to the grave, because that is a righteous wali (close friend of Allah)?

Answer:
This is not permissible. It is not permissible to make du'a' (supplication) at graves, nor to pray at graves, because this is a means to shirk (associating partners with Allah). My brother, make du'a' (supplication) to Allah in the mosque, make du'a' (supplication) to Allah in any place, or at the grave. The grave is not a place for du'a' (supplication) except for the deceased. Making du'a' (supplication) for the deceased, yes, you make du'a' (supplication) for him. But making du'a' (supplication) for yourself at the grave, this is not permissible. This is among the means to shirk (associating partners with Allah).
