28-4 (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on the authority of Al-Hassan ibn Ali al-Zaytooni and Muhammad ibn Ahmad ibn Abi Qatada, on the authority of Ahmad ibn Hilal, on the authority of Sa’eed ibn Soleiman, on the authority of Soleiman ibn Ja’far al-Ja’fari, “I asked Al-Ridha (s), ‘Will the Earth be left without a Proof?’ The Imam (s) said, ‘No. If the Earth is left without a Proof for even a moment, it will take in all its residents.’”
