Introduction

Irshad al-'Aql al-Salim ila Mazaya al-Kitab al-Karim — commonly known as Tafsir Abi al-Su'ud — is one of the masterworks of Ottoman-era Qur'anic scholarship. Its author, Abu al-Su'ud Muhammad ibn Muhammad al-'Imadi (d. 982 AH / 1574 CE), served as Shaykh al-Islam of the Ottoman Empire for nearly thirty years under Sultan Suleiman the Magnificent and his successors. Born in 896 AH / 1490 CE near Constantinople, he rose through the ranks of the scholarly establishment to become the preeminent religious authority of his era, issuing fatwas that shaped the legal and spiritual life of the empire.

Abu al-Su'ud was a Hanafi jurist and a master of the Arabic linguistic sciences, and both of these orientations permeate his tafsir. The title itself — "Guiding the Sound Intellect to the Merits of the Noble Book" — captures his ambition: to bring the reader to an appreciation of the Quran not merely through transmitted reports, but through the beauty and precision of its language. The work engages closely with the earlier tafsir of al-Zamakhshari, the Kashshaf, borrowing its grammatical and rhetorical method while carefully correcting its Mu'tazilite theological positions from a Sunni Maturidi standpoint.

The tafsir is celebrated for its extraordinary command of Arabic rhetoric (balagha), its elegant prose, and its subtle analysis of how Qur'anic phrasing achieves its intended meanings. Abu al-Su'ud pays sustained attention to word choice, sentence structure, and the inter-relations between verses, demonstrating how the apparent simplicity of the Qur'anic text conceals layers of rhetorical precision. Jurists will find systematic attention to legal derivation from the text, particularly in verses bearing on Hanafi fiqh, while students of the literary sciences will find a model of careful stylistic analysis rarely matched in the tafsir tradition.

The work spans eight large printed volumes and covers the entire Quran. It was completed around 950 AH and quickly became a standard reference in Ottoman madrasas, where it was often studied alongside the Baydawi commentary. Later scholars of the Eastern and Western Islamic traditions relied on it heavily; al-Alusi's Ruh al-Ma'ani, composed three centuries later, explicitly builds upon its contributions. The tafsir was also transmitted to non-Ottoman lands and exercised influence across the Hanafi scholarly world from the Balkans to the Indian subcontinent.

For readers of Ahl us-Sunnah wal-Jama'ah, Tafsir Abi al-Su'ud represents a high-water mark of the classical tradition: rigorous in its grammar, grounded in sound Sunni theology, attentive to legal implications, and alive to the spiritual and aesthetic dimensions of the Qur'anic text. It stands as an indispensable resource for anyone seeking to understand how the Ottoman scholarly tradition engaged the word of Allah with the full weight of the Arabic sciences.
