It is narrated from Sayyiduna Mu'awiyah bin Abi Sufyan (may Allah be pleased with him); he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "After me there will be rulers who will speak from their pulpits (in sermons), and their words will not be refuted; (then) they will plunge headlong into Hell just as monkeys plunge."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Qabil except Dimam bin Isma'il."
