Musnad Ahmad 30:1339

Yunus and Surayj narrated to us, they said: Fulayh narrated to us, from Sa’id ibn ‘Ubayd ibn al-Sabbaq, from Abu Hurayrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Before the Hour, there will be years of deception, in which the truthful one will be belied, and the liar will be believed, and the trustworthy one will be betrayed, and the treacherous one will be trusted, and the Ruwaybidah will speak." Surayj said: "And in them, the Ruwaybidah will be looked to [for counsel]."
