سنن النسائي

It was narrated that Qabisah bin Mukhariq said: "I heard the Messenger of Allah (ﷺ) says: 'It is not right to ask (for help) except in three cases: A man whose wealth has been destroyed by some calamity, so he asks until he gets enough to keep him going, then he refrains from asking: a man who undertakes a financial responsibility, and asks for help until he pays off whatever needs to be paid; and a man concerning whom three wise men from his own people swear by Allah that it is permissible for so-an-so to ask for help, so he asks until he has enough to be independent of means, then he refrains from asking. Apart from that. (asking) is unlawful."'
