From Sahih Muslim (Hadith 2405):
Salim b. Abdullah b. 'Umar reported on the authority of his father ('Abdullah b. 'Umar) that he had heard 'Umar b. Khattab (Allah be pleased with him) saying:The Messenger of Allah (ﷺ) gave me a gift, but I said: Give it to one who needs it more than I. He gave me wealth for the second time but I said: Give it to one who needs it more than I. Upon this the Messenger of Allah (ﷺ) said: Take out of this wealth which comes to you without your being avaricious and without begging, but in other circumstance's do not let your heart hanker after it
