Shams al-Dīn Muḥammad ibn Ashraf al-Ḥusaynī al-Samarqandī, an unknown logician of the seventh century AH, has an effective role in the growth and development of Sinai (Avicennism) logic in the Islamic world. Examination of his logical views shows his influence on the thoughts of some logicians, especially Qutb al-Din al-Razi. In addition to expanding some of Ibn Sina’s (Avicenna) innovations, he has certain logical views. Adherence to Ibn Sina’s system of logistics, simplification of affirmation (assertion) or negation of the composition of affirmation (assertion), solving the whole problem of false theology, distinguishing between different instances (referents) of the necessity of description and dividing it into three types, adding mental condition in negative conversion (even conversion or converse) in inversion of subject which is nonexistent attribute or affirmative inversion of attribute (predicate) which is nonexistent subject is one of the logical thoughts of Shams al-Dīn al-Samarqandī. The present article, while mentioning and examining these opinions, in discussing the simplicity of affirmation, mentions and examines Allāma Tabataba'i’s innovative view on the number of parts of the proposition, which in his view is not the Hokmieha (order, verdict ratio of the main parts of the proposition.
