يٰأَيُّهَا الَّذينَ ءامَنوا لا يَسخَر قَومٌ مِن قَومٍ عَسىٰ أَن يَكونوا خَيرًا مِنهُم وَلا نِساءٌ مِن نِساءٍ عَسىٰ أَن يَكُنَّ خَيرًا مِنهُنَّ ۖ وَلا تَلمِزوا أَنفُسَكُم وَلا تَنابَزوا بِالأَلقٰبِ ۖ بِئسَ الِاسمُ الفُسوقُ بَعدَ الإيمٰنِ ۚ وَمَن لَم يَتُب فَأُولٰئِكَ هُمُ الظّٰلِمونَ
“Believers, let not a group of you mock another. Perhaps they are better than you. Let not women mock each other; perhaps one is better than the other. Let not one of you find faults in another nor let anyone of you defame another. How terrible is the defamation after having true faith. Those who do not repent are certainly unjust”
[11:49]
