(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 had said: “The Prophet (S) had given Ali 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 to open the second and to do according to it. Then al-Hasan is to give it to al-Husayn to open the third and to do according to it and then from one to another of the progeny of al-Husayn .”
