Surah Al-Hujraat Verse 11 - English Translation by Dr Munir Munshey
Surah Al-Hujraatيَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا يَسۡخَرۡ قَوۡمٞ مِّن قَوۡمٍ عَسَىٰٓ أَن يَكُونُواْ خَيۡرٗا مِّنۡهُمۡ وَلَا نِسَآءٞ مِّن نِّسَآءٍ عَسَىٰٓ أَن يَكُنَّ خَيۡرٗا مِّنۡهُنَّۖ وَلَا تَلۡمِزُوٓاْ أَنفُسَكُمۡ وَلَا تَنَابَزُواْ بِٱلۡأَلۡقَٰبِۖ بِئۡسَ ٱلِٱسۡمُ ٱلۡفُسُوقُ بَعۡدَ ٱلۡإِيمَٰنِۚ وَمَن لَّمۡ يَتُبۡ فَأُوْلَـٰٓئِكَ هُمُ ٱلظَّـٰلِمُونَ
Oh you who believe! Let not one ethnic group ridicule another ethnic group. It may just be that those being mocked are actually better. Similarly, do not let (some) women deride other women, because the women being laughed at, may happen to be better. Do not defame or slander each other. Do not yell (racial, ethnic or other) slurs and epithets at each other. After entering faith, it is not right to insult others with disdainful names. Those who fail to repent and desist are really the evildoers
