It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Soon after me there will be rulers who will be given wisdom upon their pulpits, but when they come down (from the pulpit), that wisdom will be snatched away from them; their hearts and their bodies will be worse than carrion."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mughith (may Allah have mercy on him), who is Ibn Sumayy (may Allah have mercy on him), except Layth (may Allah have mercy on him), and Sa'id bin Maslamah (may Allah have mercy on him) is alone in narrating it."
