Sa'eed Jariri (Radiallahu anhu) says:
"I heard Abu Tufayl (Radiallahu anhu) say: "There is no one left on the face of this Earth, besides me who had seen Rasulullah (Sallallahu alaihe wasallam)." I asked him to describe to me the noble features of Rasulullah (Sallallahu alaihe wasallam). He said: "Rasulullah (Sallallahu alaihe wasallam) had a white complexion, which was slightly reddish, and had a medium sized body.": (ES)
