(V.42:45) Narrated Anas bin Mâlik رضي الله عنه: A man said, "O Allah’s Prophet (صلى الله عليه وسلم)! Will Allah gather a disbeliever prone on his face on the Day of Resurrection?" He صلى الله عليه وسلم 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?" (Qatâdah, a subnarrator, said : "Yes, by the Power of Our Lord!") (Sahih Al-Bukhari, Vol.6, Hadîth No.283).
