لِلْفُقَرَآءِ ٱلَّذِينَ أُحْصِرُوا۟ فِى سَبِيلِ ٱللَّهِ لَا يَسْتَطِيعُونَ ضَرْبًۭا فِى ٱلْأَرْضِ يَحْسَبُهُمُ ٱلْجَاهِلُ أَغْنِيَآءَ مِنَ ٱلتَّعَفُّفِ تَعْرِفُهُم بِسِيمَٰهُمْ لَا يَسْـَٔلُونَ ٱلنَّاسَ إِلْحَافًۭا ۗ وَمَا تُنفِقُوا۟ مِنْ خَيْرٍۢ فَإِنَّ ٱللَّهَ بِهِۦ عَلِيمٌ
(Alms are) for the poor who are straitened for the cause of Allah, who cannot travel in the land (for trade). The unthinking man accounteth them wealthy because of their restraint. Thou shalt know them by their mark: They do not beg of men with importunity. And whatsoever good thing ye spend, lo! Allah knoweth it.
Surah Al-Baqara(2:273)
