9:79

At-Tawba 9:79

ٱلَّذِينَ يَلْمِزُونَ ٱلْمُطَّوِّعِينَ مِنَ ٱلْمُؤْمِنِينَ فِى ٱلصَّدَقَٰتِ وَٱلَّذِينَ لَا يَجِدُونَ إِلَّا جُهْدَهُمْ فَيَسْخَرُونَ مِنْهُمْ ۙ سَخِرَ ٱللَّهُ مِنْهُمْ وَلَهُمْ عَذَابٌ أَلِيمٌ

Allazeena yalmizoonal mut tawwi'eena minalmu'mineena fis sadaqaati wallazeena laa yajidoona illaa juhdahum fayaskharoona minhum sakhiral laahu minhum wa lahum azaabun aleem

He also knows (the rich that are niggardly) who taunt the believers that voluntarily give alms, they scoff at those who have nothing to give except what they earn through their hard toil. Allah scoffs at them in return. A grievous chastisement awaits them.
