This study examines the method of Allama Hilli (648–726 AH) in citing Qur’anic verses in his book Nahj al-Haqq wa Kashf al-Sidq. The aim is to elucidate the mechanisms by which he transforms the Qur’an from a “contested text” into the “ultimate arbiter” in juridical-theological disputes, and to demonstrate how this method relates to the question of social identity and the religious legitimacy of the Imāmī Shiʿa during the Ilkhanid era.

Focusing on the juridical section of the book (pp. 408–573), which contains more than 230 direct citations of Qur’anic verses, the study analyzes Allama Hilli’s approach. The findings indicate that, within the competitive context of the Ilkhanid period and in response to the need for legitimization, he succeeded in producing a Qur’an-centered discourse through the design of a three-dimensional system. An analysis of this system at three interconnected levels shows that his method goes beyond merely confirmatory citation; rather, it constitutes “argumentative-critical citation.” In this section alone, by employing terms related to “opposition” on 204 occasions, he directly subjects the views of his opponents to discursive critique nd text-based delegitimization.

Within this framework, the Qur’an serves as the and foundation of argumentation, as well as the ultimate criterion of evaluation, while other sources derive their legitimacy through conformity with it. The study further demonstrates that Allama Hilli’s method played a significant role not only in the fields of jurisprudence and theology, but also in consolidating the social identity and religious legitimacy of Shiʿism in the Ilkhanid era.
