 Shi'ite Muslim traditions in "Usul al-Kafi" mention a book called the "Mushaf of Fatimah", which speaks of Fatimah grieving upon the passing of her father.There are several versions of this tradition, but common to all are that the angel Gabriel appeared to her and consoled her by telling her things (including future events regarding her offspring) that she wrote in a book.During these revelations, Ali acted as the scribe for Fatimah.
