Jabir b 'Abdullah reported that Allah's Messenger (ﷺ) met Ibn Sa'id (Sayyad) and there were with him Abu Bakr and 'Umar and Ibn Sayyad was in the company of children. The rest of the hadith is the same.
Sahih Muslim Book 54, Hadith 111
← Previous Hadith Do you bear testimony to the fact that I am the Messenger of Allah? Thereupon he said: Do you bear testimony to the fact that I am the messenger of Allah? Thereupon Allah's Messenger (ﷺ) said: I affirm my faith in Allah and in His Angels and in His Books, and what do you see? He said: I see the throne over water. Whereupon Allah's Messenger (ﷺ) said: You see the throne of Iblis upon the water, and what else do you see? He said: I see two truthfuls and a liar or two liars and one truthful. Thereupon Allah's Messenger (ﷺ) said: Leave him He has been confounded.

Sahih Muslim Book 54, Hadith 110 Next Hadith → I accompanied Ibn Sayyad to Mecca and he said to me: What I have gathered from people is that they think that I am Dajjal. Have you not heard Allah's Messenger (may peace upon him) as saying: He will have no children, I said: Yes, of course. Thereupon he said: But I have children. Have you not heard Allah's Messenger (ﷺ) as saying: He would not enter Mecca and Medina? I said: Yes, of course. Thereupon he said I have been once in Medina and now I intend to go to Mecca. And he said to me at the end of his talk: By Allah, I know his place of birth his abode where he is just now. He (Abu Sa'id) said: This caused confusion in my mind (in regard to his identity).
