Musnad Abu Ya'la al-Mawsili 115:135

Abu Khaythama narrated to us, Mu'adh bin Hisham narrated to us, my father narrated to us, from Qatada, from Anas, that the Prophet of Allah (may Allah bless him and grant him peace) said: "It will be said to the disbeliever on the Day of Resurrection: 'Do you see, if you had the equivalent of the world in gold, would you ransom yourself with it?' He will say: 'Yes.' Then it will be said: 'You were asked for something easier than that.'"
