الَّذِينَ يَلْمِزُونَ الْمُطَّوِّعِينَ مِنَ الْمُؤْمِنِينَ فِي الصَّدَقَاتِ وَالَّذِينَ لاَ يَجِدُونَ إِلاَّ جُهْدَهُمْ فَيَسْخَرُونَ مِنْهُمْ سَخِرَ اللّهُ مِنْهُمْ وَلَهُمْ عَذَابٌ أَلِيمٌ
[9:79]
They who taunt those of the faithful who give their alms freely, and those who give to the extent of their earnings and scoff at them; Allah will pay them back their scoffing, and they shall have a painful chastisement.
Those who slander such of the believers as give themselves freely to (deeds of) charity, as well as such as can find nothing to give except the fruits of their labour,- and throw ridicule on them,- Allah will throw back their ridicule on them: and they shall have a grievous penalty.
Those who point at such of the believers as give the alms willingly and such as can find naught to give but their endeavours, and deride them - Allah (Himself) derideth them. Theirs will be a painful doom.
