Abd Khayr (may Allah have mercy on him) narrates that he heard Sayyiduna Ali (may Allah be pleased with him) say: "The Messenger of Allah (peace and blessings be upon him) went ahead of all, Sayyiduna Abu Bakr (may Allah be pleased with him) came second, and Sayyiduna Umar (may Allah be pleased with him) came third; then a fitnah (trial) engulfed us, and then what Allah willed came to pass."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Khalid (may Allah have mercy on him) except Abu al-Ahwas (may Allah have mercy on him), and no one from Abu al-Ahwas (may Allah have mercy on him) except Mu'awiyah (may Allah have mercy on him), while Muhammad bin Musaffa (may Allah have mercy on him) is alone in narrating it."
