يَا أَيُّهَا الَّذِينَ آمَنُوا لَا يَسْخَرْ قَوْمٌ مِنْ قَوْمٍ عَسَىٰ أَنْ يَكُونُوا خَيْرًا مِنْهُمْ وَلَا نِسَاءٌ مِنْ نِسَاءٍ عَسَىٰ أَنْ يَكُنَّ خَيْرًا مِنْهُنَّ ۖ وَلَا تَلْمِزُوا أَنْفُسَكُمْ وَلَا تَنَابَزُوا بِالْأَلْقَابِ ۖ بِئْسَ الِاسْمُ الْفُسُوقُ بَعْدَ الْإِيمَانِ ۚ وَمَنْ لَمْ يَتُبْ فَأُولَـٰئِكَ هُمُ الظَّالِمُونَ11
Believers, no one group of men should jeer at another, who may after all be better than them; no one group of women should jeer at another, who may after all be better than them; do not speak ill of one another; do not use offensive nicknames for one another. How bad it is to be called a mischief-maker after accepting faith! Those who do not repent of this behaviour are evildoers
