Re: Mushaf Fatima, Al-Jamia, and Al-Jafr did exist.
you changed your authentic books, if you do not have actual saying of hz. jaffer-e-saddiq rah allow me to provide correct text of his rah saying.
I asked: What is the Mushaf of Fatima (A.S.)? He replied: It is a Mushaf in which exists three times as much as in the Qur'an. I swear to Allah, there is not a single letter of the your Qur'an in it."
you missed word "your".
Whatever is the case, the bottom line is that Mushaf Fatima was a book for Ahlulbayt [as], we do not have to worry about its content.
