Hazrat ‘Abdullah (rahimahullah), the son of Imaam Ahmed (rahimahullah), narrates the following, “I saw my father take a strand from the blessed hair of Rasulullah (sallallahu ‘alaihi wasallam), place it on his lips and kiss it. I also remember seeing him place it on his eyes, and place it in water after which he drank the water, hoping for shifaa (cure and blessings).”
