It is narrated from Hazrat Hudhaifa (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: I know more about what will happen with the Dajjal than even he does. He will have with him two flowing rivers, one of which will appear to be white water and the other will appear to be blazing fire. If any of you encounters that time, he should enter the river which appears to him as fire, and immerse himself in it, then lower his head and drink its water, for it will be cool water. And the Dajjal’s left eye will be wiped out, over it will be a thick piece of skin, and between his two eyes will be written "Kafir" (disbeliever), which every literate and illiterate Muslim will be able to read.
