What is the ruling on seeking blessing from the saliva of scholars?

Question:
A questioner says: In the hadith of Sahl ibn Sa'd (may Allah be pleased with him), when the Prophet (peace and blessings be upon him) spat in the eye of Ali (may Allah be pleased with him), he asks: Is this cited as evidence for the permissibility of seeking blessing from the saliva of scholars?

Answer:
This is specific to the Prophet (peace and blessings be upon him). It is not permissible to seek blessing from anyone except the Messenger (peace and blessings be upon him), from what separates from his noble body, such as saliva, hair, or sweat. This is specific to the Messenger (peace and blessings be upon him). As for seeking blessing, the Muslims did not seek blessing from Abu Bakr, who is the best of the nation. They did not seek blessing from his hair, nor from his clothes, and they knew that this is not permissible. This is specific to the Messenger (peace and blessings be upon him). Yes.
