Battles (Kitab Al-Malahim)

Dawud :: Book 37 : Hadith 4317

Narrated Jabir ibn Abdullah:

Muhammad ibn al-Munkadir told that he saw Jabir ibn Abdullah swearing by Allah that Ibn as-Sa'id was the Dajjal (Antichrist). I expressed my surprise by saying: You swear by Allah! He said: I heard Umar swearing to that in the presence of the Apostle of Allah (peace_be_upon_him), but the Apostle of Allah (peace_be_upon_him) did not make any objection to it.
