When I came to the Prophet he was wearing two green garments, his hair was turning grey, but the grey was dyed red.
Tirmidhi transmitted it; In a version by Abu Dawud it says he had hanging locks (These locks would hang down as far as the lobes of the ears) stained with henna.
Anas told that when the Prophet was ill he came out leaning on Usama, wearing a striped garment with an end over his left shoulder, and led them in the prayer.
It is transmitted in Sharh as-sunna.
