Musnad Abu Ya'la al-Mawsili 42:360

Zuhayr narrated to us, Ubayd Allah ibn Musa narrated to us, Shayban informed us, from Firas, from Atiyyah, from Abu Sa’id al-Khudri, from the Prophet (peace be upon him), who said: "Charity is not lawful for a wealthy person, except if he has a poor neighbor and he invites him to eat with him, or a wayfarer, or [someone] in the way of Allah."
