Musnad Ahmad Hadith 20151

It is narrated from Samurah (may Allah be pleased with him) that the Prophet (ﷺ) said: The Dajjal is about to emerge, and he will be blind in his left eye, and there will be a thick nail over it. He will cure those who are born blind and those suffering from leprosy, and he will bring the dead back to life. He will say to the people, "I am your Lord." Whoever accepts this and says, "He is my Lord," will fall into tribulation, and whoever says, "My Lord is Allah," and remains steadfast upon this until the end, will be safe from his tribulation, and he will not be subjected to any trial nor any punishment. The Dajjal will remain on the earth as long as Allah wills, then Isa (Jesus) will descend from the west, and he will come and affirm the truth of the Prophet (ﷺ) and will be upon his religion, and he will kill the Dajjal. Then the Day of Judgment will draw near.
