The Quraan Majeed has commanded us to follow Rasulullah (sallallahu ‘alaihi wasallam) in all aspects of his mubaarak life. Salvation in this world and the next depends on this. Thus one should emulate Rasulullah (sallallahu ‘alaihi wasallam) in acts of ‘ibaadah, monetary dealings, social etiquette and noble character.
Good character was an outstanding and distinguishing feature of Rasulullah (sallallahu ‘alaihi wasallam). Rasulullah (sallallahu ‘alaihi wasallam) has himself declared: “I was sent to perfect good character.” (Majma‘uz Zawaaid #14201)
One of the aspects of the excellent character of Rasulullah (sallallahu ‘alaihi wasallam) was that he shunned all vulgarity. In her description of Rasulullah (sallallahu ‘alaihi wasallam), ‘Aaishah (radhiyallahu ‘anha) says: “He was not vulgar in his nature, nor would he deliberately use vulgar language”. (Saheeh Bukhaari #6029) Some people, due to their habits and the company they keep, become vulgar by nature. While speaking, vulgar words will flow out almost “naturally” due to having corrupted the pure nature that they were born with. Others, though they may not have fallen to this level, sometimes use vulgar words when in their circles. Due to the wrong company that they find themselves in, they consciously and deliberately talk in this manner to please their friends or merely because it has become a “style.” Rasulullah (sallallahu ‘alaihi wasallam) was not vulgar in his nature nor would he deliberately use vulgar words.
Therefore, a true Muslim and a true lover of Rasulullah (sallallahu ‘alaihi wasallam) must emulate him in this aspect as well. Never should he soil his tongue, in anger or in jest, with vulgar words. He should also not be a party to spreading vulgarity in any way whatsoever — by word or deed!
