Shaykh Saduq narrated in his “Ilal ush Sharae” (p 205):

COVER PAGE

Translation:

From Fudayl ibn Sakarat: I entered to Abu Abdullah (alaihi salam), and Imam asked: O Fudayl? Do you know where I was looking before? I said: No. He said: I was looking to the book of Fatima (alaihi salam), and there is no Sultan which would rule, except he mentioned (there) by his name and name of his father. And there is nothing there for children of Hasan.

Comment:

Just imagine what kind of book that should be to contain names of all rulers which would rule in this world!
