The Ruling on Seeking Blessing from the Traces of Scholars

Question:
May Allah make your appearance ugly to you. What is this blessing, and what is it that you claim as your own? What is it that you know about them and others, and what is this cleanliness? Yes. Despite their request, and despite his adherence to prayer and the soundness of his mind, seeking prayer.

Answer:
Blessing is goodness and benefit. Goodness and benefit are called blessing, and growth and increase are blessing. As for seeking blessing from a person’s sweat, hair, or saliva, this is specific to the Prophet (peace and blessings be upon him) during his lifetime. The Prophet (peace and blessings be upon him) was sought for blessing through his hair, his saliva, and his sweat. This was during his lifetime (peace and blessings be upon him); whatever separated from his body (peace and blessings be upon him) was blessed, because he (peace and blessings be upon him) is blessed. Therefore, whatever separated from him, whether sweat, saliva, or hair, became blessed, and people sought blessing through it. The Companions used to seek blessing through it. However, after his death (peace and blessings be upon him), nothing of that remained from his body (peace and blessings be upon him). The matter is concluded.
As for other people, no matter how high their virtue, they are not sought for blessing. This is specific to the Messenger (peace and blessings be upon him). There is no one in the Ummah better than Abu Bakr (may Allah be pleased with him), 'Umar, 'Uthman, 'Ali, or the rest of the Companions. It is not known that anyone ever sought blessing from any part of their bodies. This is only the practice of innovators. Therefore, it is not permissible to seek blessing from the excretions or residues of a person, no matter how high his virtue, knowledge, or worship. This was not reported from the Salaf, even if someone claims otherwise. Furthermore, this is a means to shirk (associating partners with Allah). Whatever is a means to what is forbidden is itself forbidden. The Prophet (peace and blessings be upon him), as you know, blocked the means and paths that lead to shirk. Therefore, one does not seek blessing from the traces of a person or what separated from him, no matter who he is, except the Messenger (peace and blessings be upon him), for whom this is specific (peace and blessings be upon him).
