Ibn 'Abbas reported that the Prophet, may Allah bless him andgrant him peace, said, "Whoever fashions an image will have to breathelife into it and he will be punished since he will not be able to breathelife into it. Anyone who claims to have seen a vision in a dream will haveto string two beads of barely together and he will be punished becausehe will not be able to string them together. Anyone who listens to people'sconversation when they move away from him will have molten lead pouredinto his ears."
