Anas bin Malik RA says:
"I remained in the service of Rasulullah SAW 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 SAW 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 SAW. Nor did I smell any musk or any other fragrance, more sweet smelling than the sweat of Rasulullah SAW."
This is not an exaggeration, or something to do with faith. Infact, the perspiration of Rasulullah SAW was collected and used as a fragrance. The one with whom Rasulullah SAW 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. Rasulullah SAW 's not uttering even the word 'Oof' on anything is due to his high and noble character and humbleness. He did not regard Anas RA as fulfilling or not fulfilling a duty to be something from Anas RA's own side, but something that is from Allah, and was always contented with it.
In another hadith this has also been stated that Rasulullah SAW 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 technical terms of those who allocate a portion of their life for spiritual rectification; the essence of 'Ridha bil Qadaa' (contentment and acceptance of divine decree) has a different certificate. What is used as guidance in all efforts for spiritual reform is the character and personality of Rasulullah SAW. It was perfect and most complete in all aspects. After him the state of 'All inclusive perfection' did not remain.
Therefore among the pious people of today and previous generations, a certain habit of Rasulullah SAW would be evident in one person, and with another person another habit was evident.
Here it is worth noting that this state of Rasulullah SAW was regarding his own person.
The Noble Prophet SAW's wife, Aishah RA said:
"Rasulullah SAW 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 was committed) then he surely punished the evil doer."
It can also be added from the above most hadith that the student before whom the hadith explaining the shaking of hands was mentioned, showed his desire, that he also wish to shake hands with those hands that shook the hands of Rasulullah SAW. 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.
