Muhammad b. al-Hasan b. Ahmad b. al-Walid narrated to us. He said: Al-Husayn b. al-Hasan b. Aban narrated to us from al-Husayn b. Sa`id from Muhammad b. al-Husayn al-Kinani from his grandfather from Abi `Abdillah al-Sadiq . He said:

Allah bestowed a book unto His Prophet (s) before death came to him and said: “O Muhammad! This book is your will to the nobleman of your family.” So, he said: “Who is the nobleman from my family, O Gabriel?” So, he said: “`Ali b. Abi Talib.” On the book were seals of gold. So, the Prophet (s) gave it to `Ali and ordered him to open one of its seals and to do what is [instructed] therein. So, he opened a seal, and did what was in it. Then, he gave it to his son al-Hasan , who opened a seal, and did what was in it. Then, he gave it to al-Husayn , who opened a seal, and found therein: “Take a people toward martyrdom, for they will not find martyrdom except with you. Ransom yourself for Allah.” So, he did so, and he gave it to `Ali b. al-Husayn . So, he opened his seal and found therein: “Be silent, stick to your house, and worship Allah until death comes to you.” So, he did so, and he gave it to Muhammad b. `Ali . So, he opened his seal and found therein: “Narrate to the people and give them edicts. Fear none but Allah, for none have a way to you.” Then, he gave it to me, and I opened a seal and I found therein: “Narrate to the people and give them edicts. Spread the knowledge of your Ahl al-Bayt and the honesty of your righteous forefathers. Fear none but Allah, for you are in a protective hedge.” So, I did so. Then, I will give it to Musa b. Ja`far, and then Musa will give it to the one after him; and that will continue until the rise of the Mahdi .
