It is narrated from Hazrat Mughira (may Allah be pleased with him) that regarding the Dajjal, no one has asked the Prophet Muhammad (peace and blessings be upon him) as many questions as I have. The Prophet Muhammad (peace and blessings be upon him) once said: "He will not be able to harm you in any way." I submitted, "People say that he will have a river with him and such and such things as well." The Prophet Muhammad (peace and blessings be upon him) said: "He is much more insignificant than that in the sight of Allah."
