Obscenity

Imam Ali (AS) said, Be careful of obscene language and lies, for indeed they degrade the speaker.

Imam Ali (AS) said, Using obscene language with one who is above you is destructive ignorance.

Imam Ali (AS) said, Using obscene language with one who is below you is abasing ignorance.

Imam Ali (AS) said, Using obscene language with one who is at your level is a pecking like the pecking of two cockerels, and a quarrelling like the quarrelling of two dogs, they will never separate until they are wounded or humiliated, and this is neither the act of the wise nor the practice of the intelligent; and it may be that he (your rival) shows forbearance towards you, thereby becoming greater than you and more honourable, while you remain lower than him and more contemptible.

Imam Ali (AS) said, One who uses obscene language is reviled.

Imam Ali (AS) said, One whose obscenity increases is regarded as vile.

Imam Ali (AS) said, An honourable person never uses obscene language, ever.

Imam Ali (AS) said, There is none more shameless than the one who utters obscenities.

Imam Ali (AS) said, Indeed obscene language and vulgarities are not from the morals of Islam.

Imam Ali (AS) said, One who uses obscene language cures [the envy of] his enviers [and brings them joy].

Imam Ali (AS) said, The one who is forbearing does not use obscene language.

Imam Ali (AS) said, Two people never insult each other except that the one who is more wicked of the two prevails.
