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 he himself 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.
