لِلْفُقَرَآءِ ٱلَّذِينَ أُحْصِرُوا۟ فِى سَبِيلِ ٱللَّهِ لَا يَسْتَطِيعُونَ ضَرْبًا فِى ٱلْأَرْضِ يَحْسَبُهُمُ ٱلْجَاهِلُ أَغْنِيَآءَ مِنَ ٱلتَّعَفُّفِ تَعْرِفُهُم بِسِيمَـٰهُمْ لَا يَسْـَٔلُونَ ٱلنَّاسَ إِلْحَافًا ۗ وَمَا تُنفِقُوا۟ مِنْ خَيْرٍ فَإِنَّ ٱللَّهَ بِهِۦ عَلِيمٌ
[Charity is] for the poor who are fully occupied in the cause of Allah, unable to move about in the land [for livelihood]; the one who is unaware would think that they are rich because of their self-restraint. You will recognize them by their appearance. They do not ask people importunately. And whatever wealth you give, then Allah is All-Knowing of it.
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.
