Believers! No men shall deride other men: it may well be that those [whom they deride] are better than themselves. And no women [shall deride other] women: it may well be that those [whom they deride] are better than themselves. And neither shall you defame yourselves, nor insult one another by [opprobrious] epithets. Ill-seeming is a name connoting wickedness [to be used of one] after he has believed. Those who do not repent are indeed wrongdoers.
