Musnad Abu Ya'la al-Mawsili 155:149

Al-Hasan ibn 'Arafah narrated to us, 'Abdullah ibn Idris narrated to us, from Muhammad ibn 'Amr, from Abu Salamah, from Abu Hurayrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "The heart of the old man remains young regarding the love of two things: the love of life and the love of wealth." Ibn 'Arafah said: "And I am one of them."
