Musannaf Ibn Abi Shaybah 40259 — Reports on the tribulation

It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) said: "I know better than the Dajjal himself what the Dajjal will have with him. He will have two rivers with him: one of them will appear to the eye as white water, and the other will appear to the eye as blazing fire. If anyone is faced with this situation, let him go into the one he takes to be fire, close his eyes, and then lower his head to drink, for it will be cold water. And indeed the Dajjal has an effaced eye, on which there will be a thick zafarah (a disease in which a nail-like membrane forms over the eye). Between his eyes is written Kafir (disbeliever), which every believer will read, whether he can write (and read) or cannot write (and read)."
