One night he said to me: "O Ma'mar! Last night I felt some unsteadiness in my saddle." I said: "By the One who sent you with the truth, I fastened it just as I used to fasten it before; but perhaps it was loosened by someone who wants to take this service in my place, so that you would hand it over to someone else instead of me." The Prophet (peace and blessings be upon him) said: "I am not going to do that." The narrator says: When the Prophet (peace and blessings be upon him) had sacrificed his animal at Mina, he instructed me to shave his head. The narrator says: I took the razor and stood by his head.

I said: "By Allah, O Messenger of Allah! This is a blessing and a favour of His upon me." The Prophet (peace and blessings be upon him) said: "Very well, then I will keep you on." The narrator says: Then I shaved the head of the Prophet (peace and blessings be upon him).
