It is narrated from Sayyiduna Hudhaifah bin Yaman (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: I know what the Dajjal will have with him. He will have two flowing rivers; the water of one will appear white and the other river will appear as blazing fire. If any of you faces such circumstances, he should enter the river which he sees as fire, close his eyes, lower his head, and drink from it; that will be cool water. The Dajjal’s left eye will be obliterated, there will be a thick membrane over it, and between his eyes will be written "Kafir" (disbeliever). Every literate and illiterate believer will be able to read this word.
