The Continuity of the Divine Testament Since the Time of Adam عليه السلام

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 Himyari from Muhammad bin Isa bin Ubaid from Hasan bin Ali Khazzaz from Amr bin Aban from Hasan bin Abi Hamza from his father from Abi Ja’far عليه السلام that he said: “O Abu Hamza, the earth does not remain empty from a scholar from us Ahlul Bayt who may point out if the people commit excess in religion and if they are deficient he may point out that also. And the Almighty Allah does not let this scholar leave the world till he does not leave a successor from his progeny who has the same knowledge.”
