Musnad Ahmad 1014:3

'Ali ibn al-Hasan—meaning Ibn Shaqiq—narrated to us, al-Husayn ibn Waqid narrated to me, Abu Nahik al-Azdi narrated to us, from 'Amr ibn Akhtab, who said: The Messenger of Allah (may Allah bless him and grant him peace) asked for water to drink. I brought him a vessel containing water, and there was a hair in it. I removed it, then I handed it to him. He said: "O Allah, beautify him." He said: I saw him after ninety-three years, and there was not a single white hair on his head or his beard.
