It is narrated from Hazrat Safeena (may Allah be pleased with him) that once the Holy Prophet (peace and blessings be upon him) while delivering a sermon said: "There has not been any prophet before me who did not warn his ummah about the Dajjal. Remember! His left eye will be defective and there will be a thick piece of flesh over his right eye. Between his two eyes will be written 'Kafir' (disbeliever). He will have two symbolic valleys, one of Paradise and one of Hell. If I wish, I can even tell you the names of those two prophets and their forefathers; one of them will be on his right side and the other on his left, and this will be a trial. Then the Dajjal will say: 'Am I not your Lord? Do I not give life and death?' One of the angels among them will say: 'You are lying,' but no human except his companion angel will be able to hear this. His companion will say to him: 'You have spoken the truth.' People will hear his voice and think that he is confirming the Dajjal, whereas this will be a trial. Then he will set out until he reaches Madinah Munawwarah, but he will not be allowed to enter there, and he will say: 'This is the city of that man.' Then he will leave from there and reach Shaam, and Allah Almighty will have him killed near a valley called 'Afiq'."
