'dajjal' means liar, a dajjal is a cyclops creature that lies to us. It has the word kafir written in between its eyes (kaaf faa raa) any Muslim literate or illiterate will be able to read it. It has power which Allah gave it, and abuses it. It is so powerful when it says rain, rain will come, when it says crops, all the greens will grow. It's really powerful but, it's power has limits, its power only works 3 times. The dajjal will lie that it is our god, and will have 2 rivers with it. one will appear to have flames coming out and one will look cold. it will say that the one that looks cold is heaven is paradise and the fiery one is hell. But anyone who believes in the dajjal will go to the river that looks cool, but lo! that is the real fire, anyone who goes to the river that looks fiery, will lower their head and then read the opening of Surat AL kahf. After doing this they will calmly drink the water and behold it will be cool and will be the real river of paradise, after the dajjal's reign prophet Isa (a.s) will arrive. but the dajjal knowing itself as a sinner will be frightened at first sight of the prophet. A worm will then bite the dajjal's neck and it will pass away
