And the earth is never devoid of a Qaim from among us...

And the earth is never devoid of a Qaim from among us, be he apparent or hidden and if it be without divine proof for a single day it will cave along with its inhabitants like the sea sinks along with those in it.” 7 - Narrated to us my father (r.a.) that: Narrated to us Saad bin Abdullah bin Ja’far Himyari that they said: Narrated to us Ibrahim bin Mahziyar from his brother Ali bin Mahziyar from Muhammad bin Abi Umair from Saad bin Abi Khalaf from Hasan bin Ziyad that he said: I heard Abu Abdillah (a.s.) say: “The earth can never be devoid of a scholar (Divine Proof) because neither can the system of the earth run nor can the people be reformed without it.” 8 - And from the same chain of narrators from Ali bin Mahziyar from Hasan bin Ali Khazzaz from Ahmad bin Umar that he asked Abul Hasan (Imam Kazim): “Can the earth remain without an Imam?” He replied: “No.” I asked: “It is narrated to us that it cannot be but that Allah will be furious on His servants?” The Imam said: “It cannot remain (except that) it will sink into itself.” 9 - Narrated to us my father; and Muhammad bin Hasan - may Allah be pleased with them -they said: Narrated to us Saad bin Abdullah; and Abdullah bin Ja’far, they said: Narrated to us Muhammad bin Isa and Muhammad bin Husain bin Abil Khattab from Abi Abdullah Momin and Hasan bin Ali bin Faddal from Abi Harasa from Abi Ja’far (a.s.) that he said: “If the Imam is taken away from the earth it will sink along with its inhabitants like the sea sinks along with those in it.” 10 - Narrated to us my father and Muhammad bin Hasan - may Allah be pleased with them -they said: Narrated to us Saad bin Abdullah and Abdullah bin Ja’far they said: Narrated to us Muhammad bin Isa and Muhammad bin Husain bin Abil Khattab all of them from Muhammad bin Sinan from Hamza Tayyar that he said: I heard Aba Abdillah (a.s.) say: “If none remains on the earth except two persons, one of them will be the Divine Proof” or he said, “The second of them is the Divine Proof”.

This doubt is from Muhammad bin Sinan. 11 - And through the same chain of narrators from Muhammad bin Isa from Yunus bin Abdur Rahman from Abi Sabbah from Abi Abdullah (a.s.) that he said: “Indeed Allah, the Blessed and the Mighty, does not leave the earth but that there is a scholar on it who is aware of every excess and deficiency so that if the believers observe excess in something he may return them (to the divine limits) and if they are deficient in something he may complete it for them.
