Sheikh Abd al-Qahir Jurjani (400 – 471 A.H.), the renown Iranian rhetorician, grammarian and linguist, is among the few Muslim Iranian scientists who was ahead of his scientific community and his progressive, outstanding thoughts are of more use to modern literary men and linguists than fifth century (A.H.) literary men and grammarians. Most of the works he has left behind are in the fields of syntax and rhetoric. However, an interpretation of the Quran by Jurjani with two different rectifications has been published in recent years, which has raised serious doubts about its true ascription to him. In the present article, following an analysis of various extratextual and intratextual evidence and indications, it is concluded that this interpretation cannot be the work of Abd al-Qahir Jurjani and its attribution to him is not acceptable.
