Kitab al-Arba'in lil-Nawawi fi Mabani al-Islam wa-Qawa'id al-Ahkam كتاب الأربعين للنووي في مباني الإسلام وقواعد الأحكام

Al-Arba'in al-Nawawiyyah (The Forty Hadiths of Imam al-Nawawi), formally titled Kitab al-Arba'in fi Mabani al-Islam wa Qawa'id al-Ahkam, is one of the most widely studied, memorized, and commented-upon hadith collections in Islamic history. Gathering forty-two concise yet comprehensive Prophetic traditions, Imam al-Nawawi selected narrations that encapsulate the essential principles of Islam, covering creed, worship, jurisprudence, ethics, and spiritual refinement. For centuries, it has served as a foundational text for students of Islamic knowledge throughout the Muslim world.

Significance of This Critical Edition

This critical edition explores the remarkable scholarly development of the collection across three generations of hadith scholarship. It begins with Imam Ibn al-Salah (577-643 AH), whose Ahadith al-Kulliyyah compiled twenty-seven comprehensive narrations regarded as the foundations of Islamic law and religion. Building upon this work, Imam al-Nawawi (631-676 AH) expanded the selection to forty-two hadiths, carefully arranging them into the celebrated collection that opens with the famous hadith, "Actions are judged by intentions." Later, the eminent Hanbali scholar Ibn Rajab al-Hanbali (736-795 AH) added eight further comprehensive narrations, bringing the total to fifty, and authored his renowned commentary, Jami' al-'Ulum wa al-Hikam.

Beyond presenting the authentic text, this edition includes extensive introductory studies on the history of the Forty Hadith genre, Imam al-Nawawi's methodology in selecting and arranging the narrations, and the textual genealogy linking the works of Ibn al-Salah, al-Nawawi, and Ibn Rajab. Through meticulous critical editing, manuscript comparison, and scholarly annotations, it offers readers a deeper appreciation of one of the most influential hadith collections in the Islamic tradition.
