Surah Al-Baqarah, Verse 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 عَلِيمٌ٢٧٣

[Charity is] for the poor who have been restricted for the cause of Allāh, unable to move about in the land. An ignorant [person] would think them self-sufficient because of their restraint, but you will know them by their [characteristic] sign. They do not ask people persistently [or at all]. And whatever you spend of good - indeed, Allāh is Knowing of it.
