Shama-il Tirmidhi Chapter 8, Hadith Number 13 (65).
Ibn ‘Abbaas (R.A) says that Rasulullah (S.A.W) used to say: “Choose white clothing, as it is the best clothing. White clothing should be worn whilst living, and the dead should be buried in white.”
In this hadith it is not stated that Sayyidina (S.A.W) wore white clothing. Its mention in the ‘Shamaa-il Tirmikhi’ is therefore implicit. Idt can be explained that when Sayyidina Rasulullah (S.A.W) encouraged the wearing of white clothing, then he must have worn it himself. If is clearly stated in the Bukhaari that Sayyidina Rasulullah (S.A.W) wore white clothing.
