Musnad Ahmad 32:767

Ya'la narrated to us, Isma'il narrated to us, from Nufay', from Anas ibn Malik, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no one, neither rich nor poor, except that he will wish on the Day of Resurrection that he had been given only enough to sustain him in the world."
