Shama-il Tirmidhi Chapter 8, Hadith Number 10 (62).

Baraa bin ‘Aazib (R.A) says: “I have never seen anybody more handsome in red clothing than Rasulullah (S.A.W). At that time, the hair of Rasulullah (S.A.W) reached his shoulders.

This hadith has been mentioned in the first chapter. It is repeated here because of the red-coloured clothing.
