Honorable Shaykh, may Allah grant you success. He says: What is the ruling on seeking blessing from the soil of the graves of the awliya (close friends of Allah), or by praying at their graves, or by slaughtering animals for them?

The Shaykh:
It is not permissible to seek blessing from any created being except the Messenger (peace and blessings be upon him). Seeking blessing from the separated remnants of the Messenger (peace and blessings be upon him), such as his sweat, saliva, and hair, is specific to the Messenger (peace and blessings be upon him). As for others, one does not seek blessing from any created being. Blessing is sought from Allah (Glorified and Exalted is He), and you know the story of the Children of Israel when they said: .
The story of Dhat Anwat: when they passed by some of the polytheists after the Battle of Hunayn, they were prostrating to a date palm and hanging their weapons on it. They said, "O Messenger of Allah, make for us a Dhat Anwat just as they have their Dhat Anwat," because they were new to Islam, meaning that a period had not yet passed for them to understand the religion and know it. So the Messenger (peace and blessings be upon him) said: "Indeed, these are the ways (of the people before you). You said, by Him in whose hand is my soul, just as the Children of Israel said: " So the Messenger (peace and blessings be upon him) refuted this from them.
