Musnad Ahmad 30:1302

Abu Amir narrated to us, Fulayh narrated to us, from Hilal bin Ali, from Ata bin Yasar, from Abu Hurayrah, from the Prophet, may God bless him and grant him peace, who said: "The old man grows old, and his body and heart weaken, [yet he remains] a youth regarding the love of two things: long life and wealth."
