Jalāl al-Dīn Muḥammad ibn ʿAbd al-Raḥmān al-Qazwīnī (Arabic: جلال الدين محمد بن عبد الرحمن القزويني), commonly known as Jalāl al-Dīn al-Qazwīnī (Arabic: جلال الدين القزويني; 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.
