Jalal al-Din al-Qazwini

Jalāl al-Dīn Muḥammad ibn ʿAbd al-Raḥmān al-Qazwīnī , commonly known as Jalāl al-Dīn al-Qazwīnī (; 739–666 AH/ 1267–1338 CE) was a renowned Shāfiʿī jurist, linguist, judge, preacher, and scholar of Arabic rhetoric. He is most famous for refining and popularizing the science of balāgha (Arabic rhetoric), particularly through his two influential works: Talkhīṣ al-Miftāḥ and Al-Īḍāḥ fī ʿUlūm al-Balāgha. His writings became foundational in Islamic rhetorical education from the late medieval period onward, earning him recognition as one of the most influential scholars in the history of Arabic eloquence.

Life Jalal al-Din al-Qazwini was born in 666 AH (c. 1267 CE), most likely in Mosul, although his family originated from Qazwīn in Iran—hence his nisba "al-Qazwīnī". He lived during the post-Abbasid era, a time marked by the expansion of scholarly institutions in the Islamic world. He lived in the lands of Rūm with his father and brother, where he studied and trained in jurisprudence until he was appointed as judge (qāḍī) in Rūm while still under the age of twenty.

His two principal works — Talkhīṣ al-Miftāḥ and Al-Īḍāḥ fī ʿUlūm al-Balāgha — became standard texts in madrasas across the Islamic world. Talkhīṣ al-Miftāḥ is a succinct summary of the rhetorical sections of al-Sakkākī's Miftāḥ al-ʿUlūm, focusing on the three core branches of rhetoric: maʿānī (semantics and sentence structure), bayān (figurative clarity), and badīʿ (stylistic embellishment). Its clarity and brevity made it a foundational primer, while al-Īḍāḥ served as a more detailed companion, offering elaboration and examples for advanced students.

Al-Qazwini's works became the subject of extensive commentary by later scholars, most notably al-Taftāzānī (d. 792/1390), whose al-Mutawwal on the Talkhīṣ became a core text in its own right. Through these contributions, al-Qazwini helped transform balāgha into a formal science distinct from Arabic grammar and literary criticism. His legacy endures in both the curriculum of traditional Islamic education and the broader study of Arabic eloquence.
