H 470 - Fadhl has narrated from Muhammad bin Ali from Ja’far bin Bashir from Khalid bin Amara from Mufaddal bin Umar that he said: “Once we were discussing the subject of Imam Qaim and those who died waiting for him from among us. Imam Sadiq (a.s) said
When the Qaim rises up, someone will come and announce in the grave of every believer: Your Imam has risen, if you want to join, you may do so. Otherwise you may continue to lie in the mercy of God.”
