"So, We sent this inspiration (revelation) to the mother of Moses: 'Suckle (thy child), but when thou hast fears about him, cast him into the river. " (28: 7) Some interpreters claim that Musa's (as) mother was inspired to act in such a manner; while others say that she was spoken to (by the angels) in order to follow the Divine Commands. Al-Manawi said in Al-Jame'Al-Saghir v. 2, p.
270, on the authority of Qurtubi: "(Muhaddathoon) means those who are inspired, or, whose expectations are accurate, and directed by Divine power." It can also mean those who utter true, and accurate words, those who are spoken to by angels, or those whose opinions and viewpoints always conform to righteousness as if they were inspired by the Kingdom of Heaven.
Hence, this position is a generous miracle bestowed upon a selected group of Allah's pious worshippers, and an exalted position granted to Allah's chosen ones. Thereupon, it becomes readily easy to distinguish that Fatima az-Zahra (sa) was spoken to by angels. Because “the Mistress of all women”, and the daughter of the best of all Prophets and Messengers is not any less significant than Maryam Bint Imran (as), or, Sarah, Ibrahim's (as) wife, or, Musa's (as) mother.
Of course, this shall not be misunderstood, for any of these ladies-including Lady Fatima az-Zahra (sa) were not a prophet. Furthermore, Sheikh Saduq narrated in Ilal Ash Sharaea' that Zaid Ibn ‘Ali said: "I heard Abu Abdullah (Imam Sadiq (as)) say: "Fatima az-Zahra (sa) was called "Muhaddathah" because the angels descended from Heaven, and called her as they called Maryam Bint Imran and said: "O Fatima! Allah hath chosen thee above the women of all nations."" It has been narrated in v.
10 of A-Bihar that Imam Sadiq (as) said to Abu Basir: "... We also possess Fatima's book Mushaf, and had they known about the book of Fatima!!! It is three times the size of your Qur’an; and by Allah, it has not a letter of your Qur’an; rather it was dictated and revealed to her by Allah ...."[^2] This narration needs elaborate research and explanation, for the Imam (as) compared the size of Fatima's book to the size of the most familiar book to all Muslims-the Holy Qur’an.
Thus, if the Qur’an was printed in average-sized letters on standard paper, and let us suppose that it would fill five hundreds of such pages; then Fatima's book would need fifteen hundred had it been printed according to the same standards.
