What is the ruling on one who supplicates to Allah at the grave of a wali, without believing in any of the attributes of divinity in this deceased?

Question:
He says: Honorable Shaykh, may Allah grant you success, is the one who supplicates to Allah at the grave of a wali, believing that this is a blessed place where supplication is answered, but without believing in any of the attributes of divinity in this deceased, a disbeliever?

Answer:
Look, if he supplicates at the grave, or prays at the grave, or circumambulates the grave, seeking nearness to the owner of the grave, then this is shirk (associating partners with Allah), because he has directed worship to other than Allah. But if he performs the worship at the grave for Allah, yet he thinks that this place has a blessing and that Allah accepts from him, then this is bid'ah (religious innovation) and not shirk. This is bid'ah and a means to shirk. Shaykh al-Hakimi (may Allah have mercy on him) says in his book Ma'arij al-Qubul. The intention is the prescribed worship, such as prayer or supplication. As for slaughtering for the grave, you do not say, "This is for Allah"; this is for the grave. It does not require detailed explanation. Slaughtering for the grave, making a vow for the grave, this does not require detailed explanation. There is no question that he wants the face of Allah (Glorified and Exalted is He).
