Abstract
Textual criticism seeks to generate the most accurate version of an author's manuscript based on available copies. Textual criticism became prominent in the contemporary sense during the 19th and 20th centuries. Textual criticism studies, which were conducted extensively first in the West and then in the Islamic world, resulted in the development of several approaches aiming to identify the best version of the text under examination. Among the most prominent examples of these are the genealogical method in the West and the best text method in the Islamic world. In the best text method, which is known as the most widespread examination method in textual criticism activities, which gained momentum from the mid-19th century in the Islamic world, the examiner identifies a master copy which he thinks is the closest to the text of the author and exhibits the most solid text by taking certain criteria into consideration. Apart from obvious mistakes, the examiner does not make any changes in the master copy he selects, and does not include other copies in the text, only referring to different variants of the text. The principle of "adherence to the master copy" adopted in the method aims to limit interference in the text and prevent unnecessary and erroneous processes by the examiner.
