This is what the Imam (as) meant when he said: "It is three times the size of your Qur’an." This, however, does not mean in any way that the Holy Qur’an is deficient, or, that Fatima's book out vies it, nor, does it mean that another divine book was revealed to her. In fact anyone who makes such a claim is either ignorant, or, an infidel. The word "Mushaf' does not mean "Qur’an"; rather it means volume, book, or, a collection of articles in one notebook.
When a group of Imam Sadiq's (as) companions questioned him about Fatima's book, he was quiet for a long time then explained: "Surely you search for what you need and that you need naught". Actually, Fatima lived seventy-five days after the Prophet's death; when she was intensely depressed, Gabriel would visit and condole her on the Prophet's death. He would cheer her up by mentioning the good situation her father was enjoying, and tell her what would come to pass after her death.
Imam ‘Ali (as) wrote what Gabriel said, and this is Fatima's book. In addition, Husayn Ibn Abu al-Ala reported that Imam Sadiq (as) said: "...Fatima's book, I don't claim that it is Qur’an, rather it contains what makes people need us and makes us in need of no one.
It even mentions (the legal punishment for) a lashing, half a lashing, one fourth of a lashing, and the indemnity for a scratch mark." [^3] There remains a need for an explanation of what is meant by "It was revealed to her." This explanation can be derived from the Qur’anic verses that revelation is not confined to prophets; but rather Allah, the Exalted, reveals to some chosen people as mentioned in the following verses: • "So Zakariya came out to his people from his chamber; told them by signs to celebrate God's praises in the morning, and in the evening." (19: 11) • "So, He completed them as seven firmaments in two days, and He assigned to each Heaven its duty and command." (41: 12) • 'And, behold!
