Sahih Bukhari Volume 006, Book 060, Hadith Number 283.
Narrated By Anas bin Malik : A man said, "O Allah's Prophet! Will Allah gather the non-believers on their faces on the Day of Resurrection?" He said, "Will not the One Who made him walk on his feet in this world, be able to make him walk on his face on the Day of Resurrection?" (Qatada, a sub narrator, said: Yes, By the Power of Our Lord!)
