The motive of discord in achieving derivation research By Nour Allah bin Al-Sharif Hussein Al-Tastari or Al-Shushtari (D. 1019 AH) Derivation

Abstract

The subject of derivation، especially the derivation of the active participle، was of great importance to the fundamentalists، and they paid great attention to it to the point that they wrote books and letters on it. Among these letters was the research of Sayyid al-Tastari or al-Shushtari on this subject، for which praise is given to his research، which he titled (The Motive of Discord in the Study of the Investigation of Derivation). Among these important letters that dealt with the method of research and investigation، the issue of derivation of the active participle، in which he discussed two important issues: (Is the truth of the derivative likely to be separated from the truth of the meaning derived from it، or not?)، and (It is not a condition in applying the derivative word to something that it actually has a meaning that remains. It is derived from it)، and they are two important issues of origins that were researched by major scholars. Al-Tustari came to research these two issues with all knowledge، and he studied them with the care of scholars and the scrutiny of keen researchers and the investigation of careful knowers. His scientific dissertation was full of scientific discussion and logical response that reflects a high culture. Mr. Al-Tastari، may God have mercy on him.

Therefore, this manuscript is considered one of the precious and important manuscripts because Mr. Al-Shushtari investigated the subject of derivation, and it is one of the valuable and important researches among the fundamentalists, as they were concerned with studying the meanings of words and their connotations, noting the close connection between them and derivation, and agreement in certain fixed letters that are considered the constant principles, which It is not deleted in derivations, except for phonetic and morphological reasons arising from the letters being homogeneous with each other, and what happens when they are combined with each other.
