It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The Dajjal is going to emerge, and he will be blind in the left eye, with a thick covering over it. He will heal the one born blind and the leper, and bring the dead to life, and he will say to the people: I am your lord. So whoever says: You are my lord, has fallen into trial; and whoever says: My Lord is Allah, until he dies upon that, has been protected from the trial of the Dajjal, and there is no trial upon him. He will remain on the earth for as long as Allah wills, then Isa bin Maryam (peace be upon him) will come from the direction of the west, affirming the truth of Muhammad (peace and blessings be upon him), and he will kill the Dajjal, and that will be the onset of the Hour."
