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
﴿٢٧٣﴾
سورة البقرة
(2/273) (Your spending and charity are) for the poor who are devoted themselves to the Way of Allah and cannot move about in the earth (gain their livelihood by making trade). The one who does not know them (their state) thinks that they are rich because of their chastity; you can recognize them by their mark; they do not beg from others importunately; and whatever you spend in good, surely Allah knows it well.
Surah Al-Baqarah
