Abu Hurairah (radhi Allaahu 3nhu) narrated that the Messenger of Allah (sal Allaahu 3layhi was sallam) said:

“Indeed, before the Hour (Day of Judgement) there are deceptive years -the truthful one will not be believed, the liar will be believed, the trustworthy one will be accused of betrayal, the treacherous one will be trusted, and the Ruwaibidah will speak.”

It was said, “And what is the Ruwaibidah?” He (sal Allaahu 3layhi was sallam) said:

“The man who is Tafih (insignificant, unwise, etc.), he will speak on the affairs of the general public (he will be trusted to rule and he will speak in the name of the people).”

Ahmad (2/291) Ibn Maajah (4042), and Al-Haakim (4/465).
In As-Saheeh (1787), Albaani declared that it is an authentic Hadith.
