Hudhaifa reported the Prophet as saying, "The dajjal will come forth having with him water and fire, and what mankind see as water will be fire which burns and what they see as fire will be cold, sweet water. Any of you who live till that time must fall into what they see as fire, for it is sweet, fresh water." (Bukhari and Muslim.)
