ভূমিকা
One, who speaks obscene language lacks modesty and shame, and possesses a tongue that is filthy and impure. Obscene language is prohibited and its evil effects are numerous. It ought to be realized that evil acts manifested by a person externally, is indicative of evil that exists within him internally. God does not approve of obscene language and hence a (true) Mu'min can never be foulmouthed.
Obscene language is an offshoot hypocrisy and Shaitaan, by means of this vice, seeks to develop a friend for himself.
Of course, there are ways by means of which man can protect himself from using obscene language such as binding himself by means of vows and oaths, staying away from foulmouthed individuals, engaging in the remembrance of God, recitation of lofty supplications, ethical poems and the like.[^3] The Imam’s Reaction A'mr Ibn Nu’man Ju’fi relates: Imam Sadiq (peace be upon him) had a companion, who used to constantly accompany him (peace be upon him) wherever he (peace be upon him) would go, and never separate from him (peace be upon him).
Once when the Imam (peace be upon him) was travelling to a place called Hadhaain*,* this person together with his slave, also joined the Imam. In the course of this journey, the person looked around but saw that his servant was not to be seen. Three times he looked for him but failed to locate him. On the fourth try he found him; as soon as his eyes fell upon him, he yelled out in anger: O’ Son of an adulteress! Where have you been?
As soon as these words reached the ears of the Imam (peace be upon him), he slapped his forehead and said: Subhanallah! You have ascribed an evil act to his mother! All along I had regarded you as a pious individual, however now I have realized that you have no piety. May I be made your ransom!
