Miftah al-Ulum

Miftāḥ al-ʿUlūm (Arabic: مفتاح العلوم, romanized: The Key to the Disciplines) is a 13th-century Arabic textbook authored by Abū Yaʿqūb Yūsuf al-Sakkākī (d. 626/1229). It is most notable for codifying Arabic rhetoric into a systematic structure and became one of the most influential rhetorical texts in Islamic intellectual history. The work comprises three main sections: morphology (ṣarf), syntax (naḥw), and rhetoric (balāghah), with the third section having the most lasting scholarly legacy.
