2:273
لِ لْ فُقَرَآءِ ٱلَّذِينَ أُحْصِرُ وا۟ فِى سَبِيلِ ٱللَّهِ لَا يَسْتَطِيعُ ونَ ضَرْبًا فِى ٱلْ أَرْضِ يَحْسَبُ هُمُ ٱلْ جَاهِلُ أَغْنِيَآءَ مِنَ ٱل تَّعَفُّفِ تَعْرِفُ هُم بِ سِيمَٰ هُمْ لَا يَسْـَٔلُ ونَ ٱل نَّاسَ إِلْحَافًا وَ مَا تُنفِقُ وا۟ مِنْ خَيْرٍ فَ إِنَّ ٱللَّهَ بِ هِۦ عَلِيمٌ
[Charity is] for the poor who have been restricted for the cause of Allah, 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, Allah is Knowing of it.
