The College of Islamic Sciences at the University of Karbala held the defense of a PhD dissertation entitled:
“The Grammatical Interpretation of Qur’anic Evidence in the Book Tamheed al-Qawa‘id with the Commentary on Tashil al-Fawa’id by Muhib al-Din, known as Nadhir al-Jaysh (d. 778 AH)”,
presented by researcher Hazem Hussein Saleh, in the presence of a specialized academic committee, along with a number of scholars and researchers in the fields of language and grammar.

The study aimed to analyze grammatical phenomena in the Qur’anic evidences cited by Nadhir al-Jaysh in his work, and to demonstrate the impact of such interpretations on meaning and semantics. This was done through comparing his views with those of other grammarians, and weighing them in light of Arabic grammatical principles and contextual interpretive methodology.

The researcher examined over 117 Qur’anic evidences distributed across 19 topics, focusing on grammatical directions regarding nominatives, accusatives, and genitives. He traced Nadhir al-Jaysh’s stances—whether supportive or critical of other grammarians—while recording his own scholarly opinion and preference in each issue.

Adopting a descriptive-analytical method, the study drew on grammatical and exegetical sources, highlighting the role of grammatical interpretation in understanding the Qur’anic text, and underscoring the significance of evidences in preferring certain meanings and specifying their precise implications.

The dissertation concluded that Qur’anic evidences serve as an authentic foundation for establishing grammatical rules, and that Nadhir al-Jaysh was deeply knowledgeable, distinguished by a solid scholarly approach that combined transmission, analysis, and critique. His book Tamheed al-Qawa‘id thus stands as a significant reference in Qur’anic grammatical studies.
