(3) Muhammad bin Ya’qoob narrated from Muhammad bin Yahya from someone from al-Hasan bin Musa al-Khashshab from Ja’far bin Muhammad from Karram that Abu Abdullah as-Sadiq had said: “If people are just two men, one of them will be the imam. The last one to die is the imam lest someone protests against Allah that He has left him without an authority from Him.”
