Musnad Ahmad 31:756

Muhammad ibn Ja‘far narrated to us, ‘Awf narrated to us, from Abu Nadrah, from Abu Sa‘id al-Khudri, who said: We set out in an army from Medina towards this east. He said: In the army was ‘Abdullah ibn Sayyad, and no one would travel alongside him, nor accompany him, nor eat with him, nor drink with him, and they called him the Dajjal. While I was one day alighting at a place of mine, ‘Abdullah ibn Sayyad saw me sitting, so he came until he sat beside me. He said: "O Abu Sa‘id, do you not see what the people are doing to me? No one travels alongside me, nor accompanies me, nor drinks with me, nor eats with me, and they call me the Dajjal. And you know, O Abu Sa‘id, that the Messenger of Allah (may Allah bless him and grant him peace) said: 'The Dajjal shall not enter Medina.' And I was born in Medina. And I have heard the Messenger of Allah (may Allah bless him and grant him peace) say: 'The Dajjal shall have no children born to him,' and I have had children born to me. By Allah, I have intended, because of what these people are doing to me, to take a rope, go off alone, put it around my neck, and strangle myself, so that I may find rest from these people. By Allah, I am not the Dajjal. But by Allah, if I wished, I could inform you of his name, the name of his father, the name of his mother, and the name of the village from which he will emerge."
