Musnad Ahmad 30:2056

Mu'awiyah narrated to us, he said: Za'idah narrated to us, from 'Asim, from Abu Salih, from Abu Hurairah, from the Prophet, peace and blessings of Allah be upon him, who said: "I would not love that any of you possess gold, such that there remains with me after three [days] anything of it, except for something I set aside for a debt." "Indeed, the wealthy are the ones with the least on the Day of Resurrection, except for the one who says: 'Like this, and like this, and like this, and like this'—and they are few—to his right, and to his left, and in front of him, and behind him."
