الَّذينَ يَلمِزونَ المُطَّوِّعينَ مِنَ المُؤمِنينَ فِي الصَّدَقاتِ وَالَّذينَ لا يَجِدونَ إِلّا جُهدَهُم فَيَسخَرونَ مِنهُم ۙ سَخِرَ اللَّهُ مِنهُم وَلَهُم عَذابٌ أَليمٌ

Those who criticize the believers who willingly give out in charity, and ridicule those who find nothing to give except their own efforts, God will ridicule them, and they will have a painful punishment.
