In the World Memory Documentary Heritage Program, the subject of “originality” is the first and most important criterion for assessing written heritage, including manuscripts. Therefore, without researching the originality of a copy, it cannot be used as a basis for research. In our country, the subject of manuscripts is more related to their textual value and knowledge of correction than the knowledge of manuscript, which is a relatively new science. While the two are closely related. One of the important aspects of this relationship is the orthographic critique and the acknowledgment of the antiquity and originality of the manuscripts that are to be used in the correction of a work; because trusting the dates recorded in the translation of manuscripts without researching it is a fundamental error in correcting the text.

This copy with the number 13146 is kept in the library of the Islamic Consultative Assembly of Iran and is considered as one of the treasures of that library.
