(16) Muhammad bin Ya’qoob al-Kulayni narrated from al-Husayn bin Muhammad from Ja’far bin Muhammad from al-Qassim bin Issma’eel from Yahya bin al-Muthanna from Abdullah bin Bukayr from Obayd bin Zurara that Abu Abdullah as-Sadiq had said: “Al-Qa’im disappears twice. During one of his disappearances, he attends the seasons of hajj. He sees the people but they do not see him.”
