In the Ottoman period, in addition to the main texts of nahw science written in Arab geography, some nahw science works that will appeal to the Turks and will be included in the madrasah curriculum have been written. At the beginning of these studies is the work named Izhâru'l-esrâr, which was written by Imam Birgivî, one of the Ottoman scholars of the 16th century. Izhâru'l-esrâr has been taught in Ottoman madrasas for centuries and has been the subject of many studies such as commentary, supper-commentary, mu'rib, ta'lîka and translation. One of the commentaries on İzhâru'l-esrâr is Ref'u'l-estâr fî halli muğlakâti'l-İzhâr which is written by İsmail Niyâzî and the subject of our study. In this study, we discussed this commentary which was written in a late period, in terms of its author, its method of commentary and its scientific value. This study consists of two chapters; review and the critical edition of the text. The first chapter, which is in Turkish, is consists of two parts.
