Shama-il Tirmidhi Chapter 047, Hadith Number 003 (328).

Anas bin Maalik Radiyallahu 'Anhu says: "I remained in the service (of Rasulullah Sallallahu 'Alayhi Wasallam for ten years. He never once told me 'Oof'. When I did something, he never asked me, why did you do so? When I did not do a certain task, he never asked me why I did not do it. Rasulullah Sallallahu 'Alayhi Wasallam had the best character among all people. (and also possessed the most excellent features, so much so,) that I never felt a silk cloth, nor pure silk, nor any other thing softer than the palm of Rasulullah Sallallahu 'Alayhi Wasallam. Nor did I smell any musk or any other fragrance, more sweet smelling than the sweat of Rasulullah Sallallahu 'Alayhi Wasallam".

Commentary
This is not an exaggeration, or something to do with faith. The perspiration of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam was collected and used as a fragrance. The one with whom Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam shook hands, a fragrance emitted from that hand for a whole day. It is a proven fact that by committing excess evil the body gives off a disgraceful smell. Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam not uttering even the word 'Oof' on anything is due to his high and noble character and humbleness. He did not regard Sayyidina Anas Radiyallahu 'Anhu fulfilling or not fulfilling a duty to be something from Sayyidina Anas Radyallahu 'Anhu's own side, but something that is from Allah, and was always contented with it. In another hadith this has also been stated that Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam used to say.' 'Only that shall happen that Allah wills. If it is destined to happen it shall happen'. This is the uttermost pleasure from a beloved's deed. In the technical terms of the sufis the essence of 'Rida bil Qadaa' (contentment and acceptance of divine decree) has a different certificate. There is a famous saying of Raabi'ah Basriyyah, the translation of which is, 'O Allah, if you cut me into pieces, as a result, my love for You will surely increase'. The acts of all the accomplished sufis are taken from the many noble acts of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. The personality of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam was perfect and most complete in all aspects. After him the state of 'All inclusive perfection' did not remain. Therefore among the sufis, a certain habit of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam was evident and at another place another habit was evident. Here it is worth noting that this state of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam was regarding his own person. Sayyiditina 'Aayeshah Radiyallahu 'Anha says 'Rasulullah Sallallahu 'Alayhi Wasallam never took revenge on his own behalf (or for any wrong done to him), but if a command of Allah was transgressed (i.e. haraam deed was committed) then he surely punished the evil doer'. A similar incident is also mentioned in hadith number three in the chapter on the speech of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam.

A pleasant incident: There is a surprising story regarding the last portion of the hadith under discussion, from which we find the complete love of the Sahaabah Radiyallahu 'Anhum for Sayyidina Rasulullah Sallallahu Alayhi Wasallam. That is, Sayyidina Anas Radiyallahu 'Anhu once began saying with complete love and happiness, that I shook the mubaarak hands of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam with these hands of mine. I did not feel any silken cloth or pure silk softer than the hands of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. The student before whom this hadith was mentioned, showed his desire, that I also wish to shake hands with those hands that shook the hands of Rasulullah Sallallahu 'Alayhi Wasallam. Thereafter, this chain continued in such a manner that today after more 1,350 years it is still continually practised. It is well known as the hadith of musafahah (hand shaking) as the hand shaking is continued. Shah Waliyullah Dehlavi has also mentioned this in his book 'Musalsalaat', through whom it had reached my respected ustaadh Maulana Khalil Ahmad Saahib (May Allah fill his resting place with nur).
