Those needy ones who are wholly wrapped up in the cause of Allah, and who are hindered from moving about the earth in search of their livelihood especially deserve help. He who is unaware of their circumstances supposes them to be wealthy because of their dignified bearing, but you will know them by their countenance, although they do not go about begging of people with importunity. And whatever wealth you will spend on helping them, Allah will know of it.
Ibn 'Umar (Allah be pleased with them) reported Allah's Messenger (may peace be upon him) as saying: Do not go out to meet merchandise in the way, (wait) until it is brought into the market. This hadith has been reported on the authority of Ibn Numair but with a slight change of words.
