Anas ibn Malik (may Allah be pleased with him) reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, preceding the False Messiah will be years of deception, in which the truthful are belied, the liars are believed, the trustworthy are discredited, the treacherous are trusted, and the disgraceful speak.” It was said, “Who are the disgraceful?” The Prophet said, “Little wicked men who speak about the affairs of common people.”
