Dajjal’s Fire and Water
Uqba bin Amr said to Hudhaifa (radi Allahu anhuma), "Won't you relate to us of what you have heard from Rasul Allah?" He said, "I heard him saying, "When Ad-Dajjal appears, he will have fire and water along with him. What the people will consider as cold water, will be fire that will burn. So, if anyone of you comes across this, he should fall into the thing which will appear to him as fire, for in reality, it will be fresh cold water." [Sahih Bukhari]
Dajjal is the ultimate liar. He claims to be Allah in order to cause Muslims to commit Kufr (apostasize). He threatens, kills, decieves and tempts people in various ways, all so that they leave Islam. Even the water and fire with him are lies. Muhammad (sal Allahu alaihi wa sallam) told us that should one have to choose between the two they should choose that which appears to be fire for in reality it will be water, while that which appears to be cool water will be fire.
Another hadith in Sahih Bukhari mentions that Dajjal “will bring with him what will resemble Hell and Paradise, and what he will call Paradise will actually be Hell.” Dajjal is the ultimate imposter. What he brings is just to test humankind to see who believes in him and who remains steadfast in their belief in Allah (subhana wa ta’ala). True Paradise and Hell are with Allah (subhana wa ta’ala) alone and only He has the power to put people where they truly belong.
