Having Respect For One Another Even in Speech...

"Believers, let no man among you mock another man; the man being mocked is usually superior to the man who mocks. Let no woman among you mock another woman; the woman being mocked is usually superior to the woman who mocks. Do not slander one another, nor call each other by rude names; it is wrong that someone who has embraced the faith, should be called by a rude name. Those who do not repent, are sinners."

"O ye who believe! let not some men among you laugh at others: it may be that the (latter) are better than the (former): Nor let some women laugh at others: it may be that the (latter) are better than the (former): nor defame nor be sarcastic to each other nor call each other by (offensive) nicknames: Ill-seeming is a name connoting wickedness (to be used of one) after he has believed: And those who do not desist are (Indeed) doing wrong."
