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

And from the same chain of narrators from Ali bin Mahziyar from Faddala bin Ayyub from Aban bin Uthman from Harith bin Mughaira that he said: I heard Aba Abdillah عليه السلام say: “The earth is never without a scholar who is aware of the lawful and the prohibited and what the people are needful of. And he is not in need of the people.” I asked: “May I be sacrificed on you, what is the source of his knowledge?” He replied: “From the inheritor of the Messenger of Allah صلى الله عليه وعلى آله وسلم and Ali عليه السلام.”
