يَا أَيُّهَا الَّذِينَ آمَنُوا لَا يَسْخَرْ قَومٌ مِّن قَوْمٍ عَسَى أَن يَكُونُوا خَيْرًا مِّنْهُمْ وَلَا نِسَاء مِّن نِّسَاء عَسَى أَن يَكُنَّ خَيْرًا مِّنْهُنَّ وَلَا تَلْمِزُوا أَنفُسَكُمْ وَلَا تَنَابَزُوا بِالْأَلْقَابِ بِئْسَ الاِسْمُ الْفُسُوقُ بَعْدَ الْإِيمَانِ وَمَن لَّمْ يَتُبْ فَأُوْلَئِكَ هُمُ الظَّالِمُونَ يَا أَيُّهَا الَّذِينَ آمَنُوا اجْتَنِبُوا كَثِيرًا مِّنَ الظَّنِّ إِنَّ بَعْضَ الظَّنِّ إِثْمٌ وَلَا تَجَسَّسُوا وَلَا يَغْتَب بَّعْضُكُم بَعْضًا أَيُحِبُّ أَحَدُكُمْ أَن يَأْكُلَ لَحْمَ أَخِيهِ مَيْتًا فَكَرِهْتُمُوهُ وَاتَّقُوا اللَّهَ إِنَّ اللَّهَ تَوَّابٌ رَّحِيمٌ ( 49: 11-12)

Believers! Men should not make fun of other men for they may be better than themselves and women should not make fun of other women for they may be better than themselves. And do not be disdainful to one another nor call one another with bad names. After embracing faith, even the mention of disobedience is bad. Those who do not repent from this are indeed wrongdoers. Believers! Avoid being overly speculative, for some speculations are a blatant sin and do not spy on one another. And no one among you should indulge in backbiting others. Would anyone of you like to eat the flesh of his dead brother? So, you would detest it. Fear God. God is Most Forgiving and Ever Merciful. (49:11-12)
