Musnad Ahmad 830:91

Hajjaj narrated to us, Layth narrated to us, ‘Aqil narrated to me, from Ibn Shihab, from Talhah ibn ‘Abdullah ibn ‘Awf, that ‘Iyad ibn Musafi‘ informed him, from Abu Bakrah, the brother of Ziyad through his mother. Abu Bakrah said: The people spoke much regarding the affair of Musaylimah the Liar before the Messenger of Allah (ﷺ) said anything about him. Then the Messenger of Allah (ﷺ) stood among the people and praised Allah with what He is worthy of. Then he said: "As for what follows, regarding the affair of this man about whom you have spoken much: he is a liar from among thirty liars who will emerge before the Dajjal. And there is no city that the terror of the Messiah (the False Messiah) will not enter, except for Medina. Upon every mountain pass of its mountain passes on that day will be two angels defending it from the terror of the Messiah."
