Be Nice

O you who believe, let not one group mock another, it may be that they are better than them. Nor let women ridicule other women, it may be that they are better than them. Do not defame one another, nor call each other by offensive nicknames. How evil is a name that marks one as sinful after faith. And whoever does not repent, such are the wrongdoers.

49:11O ye who believe! Let not a folk deride a folk who may be better than they (are), not let women (deride) women who may be better than they are; neither defame one another, nor insult one another by nicknames. Bad is the name of lewdness after faith. And whoso turneth not in repentance, such are evil-doers.
