It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said: The Hour will not be established until a man from my Ahl al-Bayt becomes the ruler; he will have my name. Imam Ahmad said: Sufyan bin 'Uyaynah narrated this hadith to us in a room of his house when a son of Ja'far bin Yahya or Yahya bin Khalid asked him about this hadith.
