This research investigates the concept of grammatical analogy (qiyas) in Badr al-Din al-Muradi’s Tawdiḥ al-Maqaṣid wa al-Masalik bi Sharḥ Alfiyyat Ibn Malik, focusing on his conditions for applying analogy, his views on what may not be analogized upon, and his position regarding the conflict between transmitted linguistic evidence (samaʿ) and analogy. As a core pillar of grammatical reasoning since the era of Sibawayh and the Basran school, analogy plays a vital role in achieving the inclusiveness of grammatical rules, reconciling textual examples, and safeguarding the Arabic language. The study is structured into a preface and three main sections: the preface outlines Al-Muradi’s biography, his work, and the concept of analogy; the first section analyzes the criteria governing its validity; the second explores his treatment of cases where analogy conflicts with transmission; and the third examines the obstacles that limit its application. The findings reveal that Al-Muradi rejected analogy based on anomalous or poetically constrained usages, emphasized the precedence of transmission over analogy, and held that analogy loses validity when contradicted by authentic linguistic evidence.
