لِلْفُقَرَاء الَّذِينَ أُحصِرُواْ فِي سَبِيلِ اللّهِ لاَ يَسْتَطِيعُونَ ضَرْبًا فِي الأَرْضِ يَحْسَبُهُمُ الْجَاهِلُ أَغْنِيَاء مِنَ التَّعَفُّفِ تَعْرِفُهُم بِسِيمَاهُمْ لاَ يَسْأَلُونَ النَّاسَ إِلْحَافًا وَمَا تُنفِقُواْ مِنْ خَيْرٍ فَإِنَّ اللّهَ بِهِ عَلِيمٌ
[2:273]
(Alms are) for the poor who are confined in the way of Allah-- they cannot go about in the land; the ignorant man thinks them to be rich on account of (their) abstaining (from begging); you can recognise them by their mark; they do not beg from men importunately; and whatever good thing you spend, surely Allah knows it.
(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.
(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.
