Disappearance of the expected Imam

(2) Muhammad bin Ya’qoob narrated from Muhammad bin Yahya from Muhammad bin al-Husayn from al-Hasan bin Mahboob from Iss’haq bin Ammar that Abu Abdullah as-Sadiq عليه السلام had said: “Al-Qa’im disappears twice; one is a short disappearance and the other is long. In the first disappearance some of his close Shia knows his place and in the other one no one knows his place except his guardians of his religion.”
