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, all of them said: Narrated to us Muhammad bin Isa bin Ubaid from Yunus bin Abdur Rahman from Harith bin Mughaira from Abi Abdullah عليه السلام that he said: “Allah, the Mighty and Sublime never leaves the earth without a scholar whom the people need. And he is not needful of the people as regards the knowledge of the lawful and the prohibited.” I asked, “May I be sacrificed on you, from where does he get knowledge?” He replied: “From the inheritance of the Messenger of Allah صلى الله عليه وعلى آله وسلم and Ali ibn Abi Talib عليه السلام.”
