Musnad Ahmad 30:2670

Yazid narrated to us, he said: Muhammad ibn Ishaq narrated to us, from Musa ibn Yasar, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "The needy person is not the one whom a date turns away. Rather, the needy person is the one who does not ask people, and it is not perceived that he is in need so that he might be given."
