Musannaf Ibn Abi Shayba 33:114

Abu Khalid al-Ahmar narrated to us, from Muwarriq al-Ijli, who said: The Messenger of Allah (may Allah bless him and grant him peace) recited: "Competition diverts you, until you visit the graveyards." The Messenger of Allah (may Allah bless him and grant him peace) then said: "You have nothing of your wealth except what you ate and consumed, or what you wore and wore out, or what you gave in charity and sent forth."
