It is narrated from Sayyiduna Abu Hurayrah and Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) that they both said: The Messenger of Allah (peace and blessings be upon him) delivered a (comprehensive) sermon to us before his passing. Then the narrator mentioned the whole hadith, in which there is also this (saying) that he (peace and blessings be upon him) said: "O people, there will certainly arise in this Ummah thirty liars (false claimants to prophethood), the first of whom will be the one of al-Yamamah (Musaylimah the Liar) and (the second) the one of San'a' (al-Aswad al-Ansi)."
Imam al-Harith bin Abi Usamah recorded this hadith in his Musnad, but its chain is severely weak and munkar (denounced), because the hadith scholars declared its narrator Maysarah bin Abd Rabbih a liar and fabricator, and Dawud bin al-Muhabbar matruk (abandoned).
