Musnad Ahmad 30:2216

Affan narrated to us, Abd al-Rahman ibn Ibrahim narrated to us, al-Ala’ ibn Abd al-Rahman narrated to us, from his father Abd al-Rahman, from Abu Hurairah, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The servant says: 'My wealth, my wealth,' while he only has three things from his wealth: what he ate and consumed, or what he wore and wore out, or what he gave and stored up. Anything other than that is departing and he is leaving it for the people."
