The Dajjaal will be a man from among the sons of Adam. He will have many attributes which were described in the ahaadeeth to acquaint people with him and to warn them of his evil. So when he comes, the believers will know him and will not be misled by him; they will know his features which the the Prophet (ﷺ) has told us about. These features will distinguish him from other people, so that no one will be deceived by him except those who are ignorant and whose doom has already been decreed. We ask Allaah (ﷻ) to keep us safe and sound.
Among these attributes are:
He will be a young man with a ruddy complexion, short, with thick curly hair, a wide forehead, and broad upper chest, blind or defective (mamsooh) in the right eye. This eye will be neither prominent nor sunken, and will look like a floating grape.
His left eye will be covered with a thick piece of flesh growing at the edge of his eye. Written between his eyes will be “Kaaf faa’ raa’ (K-F-R)”, in separate (Arabic) letters, or “kaafir” with the letters joined. This will be read by every Muslim, literate or illiterate.
Another of his characteristics will be that he will be sterile, with no children born to him.
There are some saheeh ahaadeeth in which the above attributes are mentioned. These ahaadeeth form part of the evidence (daleel) concerning the emergence of the Dajjaal:
From ‘Abd-Allaah ibn ‘Umar (رضي الله عنه), who said:
“The Messenger of Allaah (ﷺ) said: ‘Whilst I was sleeping, I saw myself performing Tawaaf around the Ka’bah, when I saw a dark man with straight hair, standing between two other men, with water dripping from his head. I asked, “Who is this?” They said, “The son of Maryam.” Then I turned and saw a ruddy-complexioned man, well built, with curly hair, blind in his right eye, with his eye looking like a floating grape. I asked, “Who is this?” They said, “This is the Dajjaal.” The person who looks most like him is Ibnu Qatan.’”
(Narrated by al-Bukhaari, no. 6508; Ibn Qatan was a man from Banu Mustalaq from Khuzaa’ah).
It was also narrated from Ibn ‘Umar (رضي الله عنه) that the Messenger of Allaah (ﷺ) mentioned the Dajjaal to the people and said:
“Allqah is not one-eyed, but the false messiah (al-maseeh al-dajjaal) is one-eyed, blind or defective in his right eye, with his eye looking like a floating grape…”
