2 : 273
لِلۡفُقَرَآءِ ٱلَّذِينَ أُحۡصِرُواْ فِي سَبِيلِ ٱللَّهِ لَا يَسۡتَطِيعُونَ ضَرۡبٗا فِي ٱلۡأَرۡضِ يَحۡسَبُهُمُ ٱلۡجَاهِلُ أَغۡنِيَآءَ مِنَ ٱلتَّعَفُّفِ تَعۡرِفُهُم بِسِيمَٰهُمۡ لَا يَسۡـَٔلُونَ ٱلنَّاسَ إِلۡحَافٗاۗ وَمَا تُنفِقُواْ مِنۡ خَيۡرٖ فَإِنَّ ٱللَّهَ بِهِۦ عَلِيمٌ
[Charity is] for the poor who are fully occupied in the cause of Allah, unable to move about in the land [for livelihood]; the one who is unaware would think that they are rich because of their self-restraint. You will recognize them by their appearance. They do not ask people importunately. And whatever wealth you give, then Allah is All-Knowing of it.
