لِلْفُقَرَاءِ الَّذِينَ أُحْصِرُوا فِي سَبِيلِ اللَّهِ لَا يَسْتَطِيعُونَ ضَرْبًا فِي الْأَرْضِ يَحْسَبُهُمُ الْجَاهِلُ أَغْنِيَاءَ مِنَ التَّعَفُّفِ تَعْرِفُهُم بِسِيمَاهُمْ لَا يَسْأَلُونَ النَّاسَ إِلْحَافًا ۗ وَمَا تُنفِقُوا مِنْ خَيْرٍ فَإِنَّ اللَّهَ بِهِ عَلِيمٌ (273)
(2:273) Those who are engaged so much in the cause of Allah that they cannot move about in the land to earn their livelihood and are, therefore, in straitened circumstances, specially deserve help. An ignorant person would suppose them to be well off because of their self-respect; you can know their real condition from their faces, for they are not the ones who would beg of people with importunity. And Allah will surely know whatever you will spend on them. *314
*314). The people referred to here are those who, because they had dedicated themselves wholly to serving the religion of God, were unable to earn their livelihood. In the time of the Prophet there was a group of such volunteer workers, known as Ashab al-Suffah, consisting of about three or four hundred people who had forsaken their homes and gone to Madina. They remained at all times in the company, of the Prophet, always at his beck and call to perform whatever service he required of them. They were dispatched by the Prophet on whatever expeditions he wished. Whenever there was nothing to do elsewhere, they stayed in Madina and devoted themseleves to acquiring religious knowledge and imparting it to others. Since they were full-time workers and had no private resources to meet their needs, God pointed out to the Muslims that helping such people was the best way of 'spending in the way of Allah'.
