It is narrated from Sayyiduna Safinah (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) addressed us and said: "There was no prophet before me who did not warn his Ummah about the Dajjal. He will be one-eyed; his left eye will be blind, and on his right eye there will be a thick fleshy growth (zafarah). Between his eyes will be written 'Kafir' (disbeliever). Two valleys will come out with him, one a Paradise and the other a Fire; his Paradise will (in reality) be Fire and his Fire will be Paradise. With him will be two angels resembling two of the prophets, one on his right and the other on his left, and this will be a trial for the people. He will say: 'Am I not your Lord? I give life and I cause death.' One of the two angels will say: 'You have lied,' and none of the people will hear him except his companion (the other angel). Then his companion will say to him: 'You have spoken the truth,' and the people will hear this and think that the Dajjal has spoken the truth, and that (too) will be a trial. Then he will travel until he comes to Madinah, but he will not be permitted to enter it, and he will say: 'This is the town of that man.' Then he will travel until he comes to Syria (al-Sham), and Allah, the Mighty and Majestic, will destroy him at the pass of Afiq ('Aqabat Afiq)."
