يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا يَسْخَرْ قَوْمٌ مِّن قَوْمٍ عَسَىٰٓ أَن يَكُونُوا۟ خَيْرًا مِّنْهُمْ وَلَا نِسَآءٌ مِّن نِّسَآءٍ عَسَىٰٓ أَن يَكُنَّ خَيْرًا مِّنْهُنَّ ۖ وَلَا تَلْمِزُوٓا۟ أَنفُسَكُمْ وَلَا تَنَابَزُوا۟ بِٱلْأَلْقَٰبِ ۖ بِئْسَ ٱلِٱسْمُ ٱلْفُسُوقُ بَعْدَ ٱلْإِيمَٰنِ ۚ وَمَن لَّمْ يَتُبْ فَأُو۟لَٰٓئِكَ هُمُ ٱلظَّٰلِمُونَ
Asad Quran Translation
O YOU who have attained to faith! 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.12
And neither shall you defame one another, nor insult one another by [opprobrious] epithets: evil is all imputation of iniquity after [one has attained to] faith;13
and they who [become guilty thereof and] do not repent - it is they, they who are evildoers!
The implication is that believers, whether men or women, shall never deride one another (Zamakhshari, Baydawi).
This applies no less to the faith of the one who insults than to that of the insulted (Razi): cf. 6:82 - "[those] who have not obscured their faith by wrongdoing".
Malik Quran Translation
O believers! Let no men laugh at other men who may perhaps be better than themselves; and let no woman laugh at another woman, who may perhaps be better than herself. Do not defame through sarcastic remarks about one another, nor call one another by offensive nicknames. It is an evil thing to be called by a bad name after being a believer, and those who do not repent are the ones who are the wrongdoers.
Yusuf Ali Quran Translation
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. 4929 4930
Mutual ridicule ceases to be fun when there is arrogance or selfishness or malice behind it. We may laugh with people, to share in the happiness of life: we must never laugh at people in contempt or ridicule. In many things they may be better than ourselves!
Defamation may consist in speaking ill of others by the spoken or written word, or in acting in such a way as to suggest a charge against some person whom we are not in a position to judge. A cutting, biting remark or taunt of sarcasm is included in the word lamaza. An offensive nickname may amount to defamation, but in any case there is no point in using offensive nicknames, or names that suggest some real or fancied defect. They ill accord with the serious purpose which Muslims should have in life. For example, even if a man is lame, it is wrong to address him as "O lame one!" It causes him pain, and it is bad manners. So in the case of the rude remark, "the black man".
Mustafa Khattab Quran Translation
O believers! Do not let some ˹men˺ ridicule others, they may be better than them, nor let ˹some˺ women ridicule other women, they may be better than them. Do not defame one another, nor call each other by offensive nicknames. How evil it is to act rebelliously after having faith! And whoever does not repent, it is they who are the ˹true˺ wrongdoers.
Piktal Quran Translation
O ye who believe! Let not a folk deride a folk who may be better than they (are), nor 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.
