49:11
يَٰٓ أَيُّهَا ٱلَّذِينَ ءَامَنُ وا۟ لَا يَسْخَرْ قَوْمٌ مِّن قَوْمٍ عَسَىٰٓ أَن يَكُونُ وا۟ خَيْرًا مِّنْ هُمْ وَ لَا نِسَآءٌ مِّن نِّسَآءٍ عَسَىٰٓ أَن يَكُ نَّ خَيْرًا مِّنْ هُنَّ وَ لَا تَلْمِزُ وٓا۟ أَنفُسَ كُمْ وَ لَا تَنَابَزُ وا۟ بِ ٱلْ أَلْقَٰبِ بِئْسَ ٱلِ ٱسْمُ ٱلْ فُسُوقُ بَعْدَ ٱلْ إِيمَٰنِ وَ مَن لَّمْ يَتُبْ فَ أُو۟لَٰٓئِكَ هُمُ ٱل ظَّٰلِمُونَ
O you who have believed, let not a people ridicule [another] people; perhaps they may be better than them; nor let women ridicule [other] women; perhaps they may be better than them. And do not insult one another and do not call each other by [offensive] nicknames. Wretched is the name of disobedience after [one's] faith. And whoever does not repent - then it is those who are the wrongdoers.
9:58
وَ مِنْ هُم مَّن يَلْمِزُ كَ فِى ٱل صَّدَقَٰتِ فَ إِنْ أُعْطُ وا۟ مِنْ هَا رَضُ وا۟ وَ إِن لَّمْ يُعْطَ وْا۟ مِنْ هَآ إِذَا هُمْ يَسْخَطُ ونَ
And among them are some who criticize you concerning the [distribution of] charities. If they are given from them, they approve; but if they are not given from them, at once they become angry.
9:79
ٱلَّذِينَ يَلْمِزُ ونَ ٱلْ مُطَّوِّعِينَ مِنَ ٱلْ مُؤْمِنِينَ فِى ٱل صَّدَقَٰتِ وَ ٱلَّذِينَ لَا يَجِدُ ونَ إِلَّا جُهْدَ هُمْ فَ يَسْخَرُ ونَ مِنْ هُمْ سَخِرَ ٱللَّهُ مِنْ هُمْ وَ لَ هُمْ عَذَابٌ أَلِيمٌ
Those who criticize the contributors among the believers concerning [their] charities and [criticize] the ones who find nothing [to spend] except their effort, so they ridicule them - Allah will ridicule them, and they will have a painful punishment.
