The subject of this thesis is correction and research to the logic section of the commentary on the Al-Isharat wa al-tanbihat by Nasir al-Din Hilli, although no book of him has been corrected and published so far. The focus of Nasir al-Din Hilli's footnote on the commentary of Khawaja Nasir al-Din al-Tusi is from the important and prominent book of Ibn Sina's Al-isharat, which is a complete margin from beginning to end that is, it includes the sections of logic, physics and theology. In this book, writer explains the expressions of Khajeh Tusi and sometimes the phrases of Ibn-Sina in order to complete their meaning. Of course, sometimes he expresses his views and sometimes we are faced with phrases such as Imam al-Muttalib says,  Sahib al-Matala says, al-Samarqandi says , Sheikh in al-Shifa says, etc., which confirms the aristocracy of the most important sources of Predecessor.

To correct this book, which has been arranged in the (Qal:he says / Aqul:I say) method, three manuscripts of the libraries of the Topkapi Palace Museum in Turkey and Jarullah in Turkey have been used. In this process, while transferring the differences between the manuscripts cited in the footnote, an attempt has been made to extract the sources and sources used by Nasir al-Din Hilli in his text as much as possible.

Keywords: manuscript correction, Islamic philosophy, Nasir al-Din Hilli, Nasir al-Din Tusi, Ibn Sina, Al-Isharat wa al-Tanbihat, al-Hashieh ala al-Isharat.
