Qabisa b. Mukhariq said he had become a guarantor for a payment* and he went to Allah's Messenger ﷺ to beg from him regarding it. He said, “Wait till I receive the sadaqa and I shall order it to be given you.” He then said, “Begging, Qabisa, 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 whose property has been destroyed by a calamity which has smitten him, 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, the genuineness of which is confirmed by three intelligent members of his people, to whom begging is allowed till he gets what will support life (or he said, what will provide a reasonable subsistence). Any other reason for begging, Qabisa, is forbidden, and one who engages in such consumes it as a thing which is forbidden.”** Muslim transmitted it. * The word hamala is used of an undertaking to pay a debt or bloodwit. ** The word here used is suht, for its use of Quran (5:42,62,63)
