Narrated to us Muhammad bin Hasan (r.a.): Narrated to us Husain bin Hasan bin Aban from Husain bin Saeed from Muhammad bin Hasan Kinani from his grandfather from Abi Abdullah that he said: “Indeed Allah, the Mighty and Sublime revealed on His Prophet (S) a book before his passing away and said: O Muhammad, this is your bequest which you will give to your successor in your family. The Holy Prophet (S) asked, “And who is my successor in my family, O Jibraeel?” He replied: Ali Ibne Abi Talib . There were many seals on this book. Thus the Prophet gave that book to Ali and told him to break the seal and act upon what it says. So he broke the seal and did what it said. Then he handed it on to Hasan Ibne Ali , and he broke open one seal and carried out what was in it. Then he handed it on to Husain Ibne Ali , and he broke open one seal and found in it: ‘Go forth with a group of men to martyrdom, for there is no martyrdom for them except with you; and sell your self to Allah, to Whom belong Might and Majesty.’ So he did (this). Then he handed it on to a man after him [Ali Ibne Husain ], and he broke open one seal and found in it: ‘Lower your head in silence, do not speak out, stay in your house, and worship your Lord till what is certain (death) carries you away.’ So he did (this). Then he handed it on to his son [Muhammad Ibne Ali ], and he broke open one seal and found in it: ‘Speak to the people, give them legal rulings, and disseminate the knowledge of your ancestors.’ So he did (this). Then he handed it on to his son [Ja’far Ibne Muhammad ], and he broke open one seal and found in it: ‘Speak to the people, give them legal rulings and testify for your ancestors. And do not fear other than Allah, indeed you are in the protection of Allah and in His guarantee. And he was ordered to transfer it and he transferred it to one after him and so on till [the rising of Mahdi and] the Judgment Day.”
