سنن أبي داود

Qabisah b. Mukhiriq al-Hilali said : I became a guarantor for a payment, and I came to Messenger of Allah (May peace be upon him). He said: Wait till I receive the sadaqah and I shall order it to be given to you. He then said : Begging, Qabisah, is allowable only to one of three classes: a man who has become a guarantor for a payment to whom begging is allowed till he gets it, after which he must stop (begging); a man who has been stricken by a calamity and it destroys his property to whom begging is allowed till he gets what will support life (or he said, what will provide a reasonable subsistence); and a man who has been smitten by poverty, about whom three intelligent members of his people confirm by saying: So and so has been smitten by poverty, to such a person begging is allowed till be gets what will support life (or he said, what will provide a reasonable subsistence), after which he must stop (begging). Any other reason for begging, Qabisah, is forbidden, and one who engages in such consumes it as a thing which is forbidden.
