(28) Ahmad bin Muhammad bin Sa’eed narrated from Ali bin al-Hasan from al-Abbas bin Aamir bin Rabah ath-Thaqafi from Abdullah bin Bukayr that Zurara bin A’yun had said: “I heard Abu Abdullah as-Sadiq saying: “A caller will call out from the Heaven that so-and-so is the emir and that Ali and his followers are the triumphants.” I said: “Then who will fight al-Mahdi after that?” He said: “The Satan will call out that so-and-so and his followers are the triumphants-a man of the Umayyads (Uthman).” I said: “Then who will know which the truthful is and which the liar is?” He said: “Those, who used to narrate our traditions, will know that and will know that they are with the truth.”
