Is there evidence in the Sunnah of the prescription of seeking blessing from the body of the Prophet (peace and blessings be upon him) during his lifetime and from his belongings after his death?

Question:
He says: Honorable Shaykh, may Allah grant you success, is it established in the Sunnah that it is prescribed to seek blessing from the body of the Prophet (peace and blessings be upon him) during his lifetime and from his belongings after his death? Is this established?

Answer:
Yes, it is established. What separated from his body (peace and blessings be upon him), such as his sweat, his saliva, his hair, and his clothes, one seeks blessing from it. What separated from his body (peace and blessings be upon him) is what one seeks blessing from. This is established. As for the places he passed through, or in which he prayed, or in which he sat without intention, but rather by coincidence, one does not seek blessing from them. One does not seek blessing from them. Yes.
