Sura al-Baqara 2:273

لِلْفُقَرَآءِ ٱلَّذِينَ أُحْصِرُوا۟ فِى سَبِيلِ ٱللَّـهِ لَا يَسْتَطِيعُونَ ضَرْبًا فِى ٱلْأَرْضِ يَحْسَبُهُمُ ٱلْجَاهِلُ أَغْنِيَآءَ مِنَ ٱلتَّعَفُّفِ تَعْرِفُهُم بِسِيمَٰهُمْ لَا يَسْـَٔلُونَ ٱلنَّاسَ إِلْحَافًا وَمَا تُنفِقُوا۟ مِنْ خَيْرٍ فَإِنَّ ٱللَّـهَ بِهِۦ عَلِيمٌ

lil-fuqarāʾi lladhīna uḥṣirū fī sabīli allāhi lā yastaṭīʿūna ḍarban fī l-arḍi yaḥsabuhumu l-jāhilu aghniyāʾa mina l-taʿaffufi taʿrifuhum bi-sīmāhum lā yasʾalūna l-nāsa ilḥāfan wa-mā tunfiqū min khayrin fa-inna allāha bihi ʿalīmun

(Charity is) for those in need, who, in Allah's cause are restricted (from travel), and cannot move about in the land, seeking (For trade or work): the ignorant man thinks, because of their modesty, that they are free from want. Thou shalt know them by their (Unfailing) mark: They beg not importunately from all the sundry. And whatever of good ye give, be assured Allah knoweth it well.
