The Islamic Hadith of Fatima, chronicled by Muslim, tells of al-Jassah who is “a beast who was so hairy that they could not tell its front from its back” and those who saw al-Jassah “were afraid lest it be a devil.” When asked who/what he/it is, al-Jassah replies, “go to this man in the monastery.” The man was “a huge man with his hands tied up to his neck and with iron shackles between his legs up to the ankles” who stated, “I am the Dajjal.” According to Islamic eschatology the Dajjal, aka Al-Masih ad-Dajjal (“deceiving,” “the Placebo” or “impostor”), is to appear and pretend that he is the Masih/Messiah.
The Dajjal is basically like an anti-Christ figure (or, anti-Muhammad figure which, well, of course, would actually be a pro-anti-Christ figure) and the hairy creature, al-Jassah, appears to be a “the beast” figure.
