It is known that the Iraqi hafiz in his systems was trying to contain Ibn al-Salah’s book on the sciences of hadith. Therefore, the subject of hadith sciences or the term hadith was the original material in the book, but the book is not without investigations in various sciences such as language, morphology, grammar, presentations, history, biographies, and others. It was not an abstract abbreviation, or a monotonous codification. Rather, it was distinguished by the fact that the explainer brought in it the ambiguous benefits, and the precious returns, in order to correct, correct, trace, and clarify, and the additions included in the covers of this great travel eventually completed the journey of learning the term hadith. Al-Hafiz Ibn Hajar, who also classified the science of hadith terminology as a book, perhaps we do not lie to ourselves if we say that the Iraqi Hafiz was his first subject in it, even if Ibn Hajar had the splendor of order and innovation. He has some things, as they do not violate the spirit of renewal that Al-Hafez Al-Iraqi possessed, during his explanation. The ruling here is for the majority, not for the totality.
This book contains the keys to the science of hadith, including a summary of its sciences of different materials, from dates to texts, then controlling them, then knowledge of men, then their wounding and modification, then to the colors of science, in which the reader turns among the gardens of its flowers, picking its flowers and reaps its fruits by perpetuating the consideration of this science He traced its ramifications, sniping its benefits, noticing the positions of the people concerned about it, the name of Alfiya al-Iraqi: (Al-Tasbirah and the Ticket), and its explanation afterwards, and the name of the explanation: (Sharh al-Tasbirah wa al-Tizkirah). God is the guide and conciliator to the truth, with his permission.
