Commonly known as " the false messiah ", "liar" or "the deceiver", also as "the antichrist".
In the Muslim concept:
Dajjal is the embodiment of evil. A sage once said: “Know your enemies and keep them close to you. By knowing them, you know their weakness, thus neutralizing their potency. “There are many hadiths that describe Dajjal's appearance, his height, and his powers.
Ubadah ibn Samit radiallahu anhu relates that the Prophet said “I have explained Dajjal to him, but I am afraid he did not understand it. Masih-ud-Dajjal will be short and his legs will be crooked. The hair on your head will be extremely twisted. He will have one eye, while his other eye will be flat. It will be neither deep nor salient. "
And a last Prophet said peace and blessings be upon him (peace and blessings be upon him) regarding Dajjal: “… a man with red, fat and curly skin, blind in the right eye who looks like a bulging grape”.
Bukhari:
According to the many Ahadith who describe Dajjal, the most distinctive face of his face in addition to the bulging eye will be the Arabic letters Kaaf (k), Faa (f), Raa (r), on his forehead. These letters spell Kufr (disbelief). All believers, regardless of their literacy, will decipher these letters.
It has also been proven from the hadiths that it will emerge from Syria and Iraq, and its emergence will become known when you are in Isfahan, in a place called Judea. He will be of Jewish origin and the Jews of Isfahan will be his main followers and will refer to him as the Messiah. As he moves through the world, Jews and large numbers of non-Jewish women will flock to him to witness his false miracles.
Muslim words say that those who obey the Dark Messiah will enter his paradise, which is defined as entering Hell, and those who denounce him will enter his Hell (and thus are actually entering Paradise). You will travel by means of a gigantic mule, at impossible speeds. He will cause droughts and famine on those who reject him. But the memory of the true Lord will satisfy them.
Dajjal is an anti-messianic figure, comparable to the antichrist in Christian eschatology and Armilus in medieval Jewish eschatology.
