al-Masih ad-Dajjal, Arabic for "the false messiah", is an evil figure in Islamic eschatology.He is to appear pretending to be Masih at a time in the future,
before Yawm al-Qiyamah (Judgment Day), directly comparable to the figures of the Antichrist and Armilus in Christian and Jewish eschatology, respectively.
Dajjāl is a common Arabic word the meaning "deceiving" or "the Placebo" or "impostor" Al-Masīḥ ad-Dajjāl, with the definite article al- ("the"), refers to "the deceiving Messiah", a specific end-of times deceiver.
According to hadith, Muhammad is said to have prophesied that the Masih ad-Dajjal would be the last of a series of thirty Dajjal or "deceivers" (false prophets).
Muhammad is reported to have said:
... Allah is not one eyed while Messiah, Ad-Dajjal is blind in the right eye and his eye looks like a bulging out grape.
Narrated 'Abdullah bin 'Umar: Allah's Apostle said. "While I was sleeping, I saw myself (in a dream) performing Tawaf around the Ka'ba. Behold, I saw a reddish-white man with lank hair, and water was dropping from his head. I asked, "Who is this?' They replied, 'The son of Mary.' Then I turned my face to see another man with a huge body, red complexion and curly hair and blind in one eye. His eye looked like a protruding out grape. They said (to me), He is Ad-Dajjal." The Prophet added, "The man he resembled most is Ibn Qatan, a man from the tribe of Khuza'a."
Narrated Ibn Umar: Once Allah's Apostle stood amongst the people, glorified and praised Allah as He deserved. Then, mentioning Dajjal, he said, "I warn you against him (i.e. the Dajjal) and there was no prophet but warned his nation against him. No doubt, Noah warned his nation against him but I tell you about him something of which no prophet told his nation before me. You should know that he is one-eyed, and Allah is not one-eyed."
Imam Ali was reported to have said:
His right eye will be punctured, and his left eye would be raised to his forehead and will be sparkling like a star. Only the believers will be able to read the word ‘Kufr’ [disbelief], inscribed in bold letters, on his forehead. There will be big mountains of smoke at both front and backsides of his caravan. People will anticipate food within those mountains, during the severe famine.All rivers, falling in his way, will become dry and he will call upon people in aloud voice, "O my friends come to me! I am your lord who has made your limbs and given you sustenance.
