Surah No. 49, Al Hujurat, Ayat No. 11

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 الظَّالِمُونَo

Translation :

O believers ! Some men among you should not laugh at others: it may be that they are better than the former : or some women should not laugh at others: it may be that they are better than the former : nor defame others or should not pass taunts to each other, nor call each other by bad nicknames: How bad it is to insult a brother after he has Faith : And those who do not repent, they are wrongdoers.

o وَيْلٌ لِّكُلِّ هُمَزَةٍ لُّمَزَةٍ

o إِن تُبْدُواْ خَيْرًا أَوْ تُخْفُوهُ أَوْ تَعْفُواْ عَن سُوَءٍ فَإِنَّ اللّهَ كَانَ عَفُوًّا قَدِيرًا

There is no harm if you describe the doings of the oppressor( Tyrant) or if you hide it or forgive it, then know that having all strenghts! Allah is ever Forgiving, Powerful.
