Musnad Ahmad 32:1636

Affan narrated to us, Hammad narrated to us, from Thabit, from Anas, that the Messenger of Allah, peace and blessings of Allah be upon him, used to frequently say: "O Allah, give us in this world [that which is] good, and in the Hereafter [that which is] good, and protect us from the punishment of the Fire."
