(4) Ali bin Ahmad al-Bandaneeji narrated from Obaydillah bin Musa from Muhammad bin Ahmad al-Qalanisi from Muhammad bin al-Waleed from Younus bin Ya’qoob that Abu Abdullah as-Sadiq عليه السلام had said: “The Prophet صلى الله عليه وعلى آله وسلم had given Ali عليه السلام a book sealed with twelve seals and said to him: “Open the first seal and do according to it and then give it to al-Hasan عليه السلام to open the second and to do according to it. Then al-Hasan عليه السلام is to give it to al-Husayn عليه السلام to open the third and to do according to it and then from one to another of the progeny of al-Husayn عليه السلام.”
