Shama-il Tirmidhi Chapter 001, Hadith Number 004 (004).
Baraa bin Aazib (Radiallahu Anhu) reports: "I never seen someone with long hair and red clothing more handsome than Rasullullah (Sallallahu alaihe wasallam). His hair reached his shoulders. The portion between his two shoulders was wide. He was neither very tall nor very short".
The description of the hair of Sayyidina Rasullullah (Sallallahu alaihe wasallam) in this hadeeth is different one mentioned before. There it is stated that his hair reached his ear-lobes. In reality there is no difference between the two hadeeth, as the hair does not remain the same length but grows. Sometimes the hair was shortened, sometimes longer hair was kept.
