Surah Al-Baqarah — Ayah 273 (2:273)
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 عَلِيمٌ ٢٧٣
English translation (Saheeh International)
[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.
Brief commentary
You should spend on those poor people who, because they are busy striving in Allah’s path, are unable to travel to earn a living. Due to their not asking, a person that is unaware will think that they are not in need. However, the person who knows will recognise them by the signs that are apparent on their body and clothing. They are unlike other poor persons who beg persistently. Allah knows of any good or wealth you spend and He will give you a great reward for it.
