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

It is they who criticize the believers who give freely and those who can only give a little with great effort: they scoff at such people, but it is God who scoffs at them- a painful punishment awaits them.
Those who defame such of the believers who give charity (in Allâh’s Cause) voluntarily, and such who could not find to give charity (in Allâh’s Cause) except what is available to them - so they mock at them (believers); Allâh will throw back their mockery on them, and they shall have a painful torment.
