2. A number of our people has narrated from Ahmad ibn Muhammad from ‘Umar ibn ‘Abd al-‘Aziz from Hammad Ibn ‘Uthman who has said that he heard Abu ‘Abdallah عليه السلام say the following: "The heretics will appear in the year one hundred twenty eight (745/746AD) because I have found it in the Mushaf of Fatima عليه السلام.” I asked the Imam, “What is Mushaf of Fatima?” The Imam said, “When Allah took the Holy Prophet صلى الله عليه وعلى آله وسلم from this world, it caused such a degree of grief to Fatima عليه السلام that only Allah, the Most Holy, the Most High, knows its extent. Allah then sent an angel to her to offer solace and speak to her. She complained about it to Amir al-Mu’minin Ali عليه السلام who asked her to inform him whenever she would find the angel speak to her. She then informed him when the angel came to speak. Amir al-Mu’minin Ali عليه السلام then would write down all that he would hear of the conversations of the angel so much so that his notes took the shape of a whole book.” The Imam عليه السلام then said, “There was nothing in it of the knowledge of the lawful and unlawful matters but it had the knowledge of things that had happened and things to happen in future.”
