Shama-il Tirmidhi Chapter 8, Hadith Number 1 (53).
The ‘ulama have written different reasons for Sayidina Rasulullah Sallallahu ‘Alayhi Wasallam preferring to wear a qamis (Thowb, kurtah). Some say it is because it covers the body well and covers it better than a lungi etc. Some say because it is ‘qumait’ and besides it is less of a burden on the body, whereas a sheet has to be straightened every now and then. Some are of the opinion that it does not create pride in a person, as other clothing does. According to this humble servant the reason is because it covers the satr well, and the same time it is neat, whereas in some clothing there is less beauty, like the lungi, or it does not cover the satr well, like the top sheet. The eighth hadith in this chapter seems contrary to this hadith. It shall be compared and reconciled there.
