Commentary.
Mulla 'Ali Qaari relates from Dimyaati that the qamis of Sayidina Rasulullah Sallallahu 'Alayhi Wasallam was made of cotton and was not very long, nor were the sleeves long. Bayjuri has written that Sayidina Rasulullah Sallallahu 'Alayhi Wasallam had only one qamis. It is reported from Sayyiditina 'Aayeshah Radhiyallahu 'Anha that: "Rasulullah Sallallahu 'Alayhi Wasallam did not leave any of the morning food for the evening, nor any of the evening food for the morning. He possessed only one each, of a lungi, qamis, sheet (body wrap), shoes or any other clothing. He did not have a pair of any of these".

Munaawi relates from Sayyidina Ibn 'Abbaas Radiyallahu 'anhu that, 'The qamis (thowb, kurtah) of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam was not very long, nor were its sleeves long. In another hadith of Sayyidina Ibn 'Abbaas Radiyalia anhu it is stated that the qamis of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam was above the ankles. 'Allaamah Shaami says: 'It should reach halfway down the calf'.
