Musnad Ahmad 830:56

'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from Talha ibn 'Abd Allah ibn 'Awf, from Abu Bakrah, who said: The people spoke much about Musaylimah before the Messenger of Allah (peace and blessings of Allah be upon him) said anything about him. Then the Messenger of Allah (peace and blessings of Allah be upon him) stood up to deliver a sermon and 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 Hour. And there is no town but that the terror of the False Messiah (al-Masih al-Dajjal) will reach it."
