Narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him): The Messenger of Allah (peace and blessings be upon him) said: There will be no birth to the parents of Dajjal for thirty years, after which a one-eyed child will be born to them. (In another narration: His navel will already be cut and he will be circumcised by birth.) He will be a child who brings much harm and little benefit; when he sleeps, his eyes will sleep but his heart will remain awake. Then the Prophet (peace and blessings be upon him) described his parents: his father will be tall and weak-bodied, his nose will be like a beak, and his mother will have large breasts, her bosom being big and long. Later, we were informed that a child had been born to the Jews in Madinah. I (Abu Bakrah) and Sayyiduna Zubair bin Al-Awwam (may Allah be pleased with him) went to his parents; we saw in them the signs described by the Messenger of Allah (peace and blessings be upon him). Meanwhile, the child was lying in the sun covered with a sheet, and his humming could be heard. We asked his parents some questions; they told us: For thirty years we had no children, then a one-eyed child was born to us, who was very harmful and of little benefit. Then, as we left, we passed by the child; I removed the cloth from his head and he said: What were you talking about? We said: Were you listening to our conversation? He said: Yes, my eyes sleep but my heart does not sleep. He was Ibn Sayyad.

It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him), he says: If I were to swear ten times that Ibn Sayyad (i.e., Ibn Siyyad) is the Dajjal, this would be more beloved to me than swearing once that he is not the Dajjal. The matter is that the Messenger of Allah (peace and blessings be upon him) sent me to his mother and said: Go and ask her how long she carried this child in her womb. I went to her and asked her about this, and she informed me that she carried him for twelve months. Then the Prophet (peace and blessings be upon him) sent me again and said: Go and ask what his cry was like at birth. I went to her again and asked her this question, and she informed me that his cry was like that of a one-month-old child. Then the Prophet (peace and blessings be upon him) said to him: I have concealed something in my heart (what is it)? Ibn Sayyad said: You have concealed from me the words "Khatm Shatin 'Afraa' wa al-Dukhan." He wanted to say "al-Dukhan," but he did not have the strength to say the whole word, so he said: "al-Dukh... al-Dukh..." The Messenger of Allah (peace and blessings be upon him) said: Be humiliated, you will not be able to go beyond your status.
