Ibn Umar reported: The Messenger of Allah ﷺ stood among the people and praised Allah in a way which is worthy of him, and mentioned the Antichrist (Dajjal), saying: I warn you of him, and there has been no prophet who has not warned his people about him, and Noah also warned his people about him. But I tell you about him a word which no Prophet had told his people: you should know that he will be blind in one eye, and Allah is not blind is one eye.

Anas bin Malik reported the Prophet ﷺ as saying: No prophet was sent who had not warned his people about the one-eyed. Between his eyes will be written “infidel” (kafir).

Narrated Ubadah ibn as-Samit: The Prophet ﷺ said: I have told you so much about the Dajjal (Antichrist) that I am afraid you may not understand. The Antichrist is short, hen-toed, woolly-haired, one-eyed, an eye-sightless, and neither protruding nor deep-seated. If you are confused about him, know that your Lord is not one-eyed. Abu Dawud said: Amr bin Al-Aswad was appointed a judge.

Narrated Abu Ubaydah ibn al-Jarrah: I heard the Prophet ﷺ say: There has been no Prophet after Noah who has not warned his people about the antichrist (Dajjal), and I warn you of him. The Messenger of Allah ﷺ described him to us, saying: Perhaps some who have seen me and heard my words will live till his time. The people asked: Messenger of Allah! what will be the condition of our hearts on that day? Like what we are today? He replied: Or better.
