His complexion is the color of an Arab's.
(Small Book of Portents of the Mahdi of the End Times, 24)
Note: The Arab complexion is a mixture of red and white.
The Mahdi is Arab in coloring.
(al-Haythami, Al-Qawl al-Mukhtasar, pp, 15-75)
Anas ibn Malik said this about the Prophet's (saas) complexion: He was white, but a brownish white. (Ibn Kathir, Shamail Rasul, p. 28)
Not dark brown and not white, but with a little red. The Servant of Allah's (saas) color is as white as that of someone who has just left the baths and grown a little pink, a color the like of which nobody else will have at that time. In other words, his complexion is a radiant white mixed with pink.
(Ibn Kathir, Shamail Rasul, p. 18)
