Knowledge of the science of the transcriber and the abrogated is a great matter, and the scholars have agreed that no one may explain or fatwy in something from the Book of God or the Sunnah of His Messenger until there are many conditions, including the knowledge of the transcriber and the abrogated. That is why the scholars have taken care of this science a lot, as it is a very important science in proving the legal rulings and raising them and knowing the applicant from the late. Therefore, this book is considered unique in its material.
