Musnad Abu Ya'la al-Mawsili 115:169

Abu Khaythama Mu'adh ibn Hisham narrated to us, my father narrated to me, from Qatada, from Anas, that the Prophet of Allah (may Allah bless him and grant him peace) said: The son of Adam grows old, and two things grow young within him: greed for wealth and length of life.
