When Imam Yahya ibn Sharaf an-Nawawi completed his forty-two foundational hadiths, he created an educational catalyst that energized Islamic scholarship for over seven centuries. Because the Prophet Muhammad ﷺ was endowed with Jawami' al-Kalim—the miraculous ability to express boundless spiritual and legal wisdom within concise verbal expressions—the 40 Hadiths inspired dozens of master commentaries (Shuruh). For any student seeking to unlock the inner ocean of an-Nawawi's collection, three monumental classical works form the indispensable foundation.
1. The Crown Jewel: Jami' al-'Ulum wal-Hikam by Ibn Rajab al-Hanbali
Written by al-Hafiz Zayn ad-Din Abu al-Faraj Abdur-Rahman ibn Ahmad ibn Rajab al-Hanbali (736–795 AH), Jami' al-'Ulum wal-Hikam fi Sharh Khamsina Hadithan min Jawami' al-Kalim (The Compendium of Knowledge and Wisdom in Explaining Fifty Hadiths of Comprehensive Words) is universally recognized by hadith masters as the absolute finest, most comprehensive commentary ever authored on the collection.
Why Did Ibn Rajab Add 8 Hadiths to Make it 50?
Ibn Rajab recognized that an-Nawawi's collection had incorporated 26 hadiths originally selected by Ibn as-Salah, expanding them to 42. Seeking to complete the universal foundational maxims of the Sacred Law, Ibn Rajab appended eight essential hadiths—including the hadith of Mu'adh ibn Jabal on deeds that admit to Paradise, the hadith on guarding the rights of Allah, and the hadith on modesty—bringing the total to a complete fifty traditions, each accompanied by an encyclopedic commentary.
Hallmarks of Ibn Rajab's Method:
- Textual Variants (Riwāyāt): Exhaustively collects all authentic and weak variant wordings across the Musnad, Mu'jam, and Sunan traditions, demonstrating how subtle differences clarify obscure sentences.
- Early Salaf Sayings: Integrates thousands of rare, verified statements from the Sahabah, Tabi'in, and early ascetics of Basra, Kufa, Medina, and Syria.
- The Balance of Law and Raqa'iq: Effortlessly navigates technical legal rulings (Fiqh) while weaving in tears-inducing spiritual heart-softeners (Raqa'iq) and psychological insights into the diseases of the ego (Nafs).
2. The Legal-Logical Manual: Sharh Ibn Daqiq al-Id
Authored by the formidable polymath Taqi ad-Din Abu al-Fath Muhammad ibn Ali ibn Wahb, known as Ibn Daqiq al-Id (625–702 AH)—who served as the Chief Judge of Egypt and was celebrated as the Mujaddid (Reviver) of the 7th Islamic century.
Unlike Ibn Rajab's expansive literary compendium, Ibn Daqiq al-Id’s commentary is characterized by rigorous mathematical conciseness, structural discipline, and laser-like legal precision. It is the premier textbook memorized and studied across Islamic colleges and traditional seminaries from Cairo to Damascus.
Hallmarks of Ibn Daqiq al-Id's Method:
- Usuli Jurisprudential Extraction: Applies the principles of Islamic legal theory (Usul al-Fiqh) to extract maxims, legal causes ('Ilal), and derived rulings with razor-sharp logic.
- Grammatical & Morphological Rigor: Deconstructs Arabic grammatical particles (such as innama, ba', lam, and conditional clauses), demonstrating how sentence syntax dictates legal obligations.
- Brevity without Obscurity: Synthesizes massive theological issues into dense, memorable paragraphs that prevent the student from losing the core thread of the hadith.
3. The Shafi'i Masterpiece: Al-Fath al-Mubin by Ibn Hajar al-Haytami
Authored by Shihab ad-Din Ahmad ibn Muhammad ibn Hajar al-Haytami al-Makki (909–974 AH), one of the foremost final authorities in the later Shafi'i legal school who spent his life teaching in the sacred precincts of Mecca.
His work, Al-Fath al-Mubin bi-Sharh al-Arba'in (The Clear Manifest Victory in Commenting on the Forty), represents the mature scholastic flowering of Late-Mamluk and Early-Ottoman Islamic scholarship. It provides an exhaustive line-by-line textual gloss that directly addresses every potential theological objection, grammatical nuance, and jurisprudential ambiguity.
Hallmarks of Al-Haytami's Method:
- Shafi'i Legal Canonization: Systematically connects every hadith to its definitive position within the Shafi'i Madhhab, referencing Imam an-Nawawi's own legal encyclopedias (Al-Majmu' and Rawdat al-Talibin).
- Theological Refinements: Resolves delicate questions regarding the Divine Attributes, predestination, and eschatology according to classical orthodox Sunni methodology.
- Scholastic Dialogue: Directly engages, verifies, or critiques prior commentators—including Ibn Daqiq al-Id, al-Zarkashi, and al-Taftazani.

5. Modern and Contemporary Commentaries
In the modern era, prominent scholars have continued the tradition of commenting upon an-Nawawi's Forty, making its teachings accessible to global audiences facing modern secular realities:
- Sharh al-Arba'in by Shaykh Muhammad ibn Salih al-'Uthaymeen (d. 1421 AH): Celebrated for its accessible, contemporary pedagogical style. He breaks each hadith into numbered foundational points (Fawa'id) and directly answers contemporary ethical, medical, and financial questions.
- Fath al-Qawiyy al-Matin by Shaykh 'Abd al-Muhsin al-'Abbad: A concise contemporary masterpiece by the grand hadith scholar of the Prophet's Mosque in Medina, providing rigorous yet streamlined isnad evaluation and practical guidance.
- English Translations & Anthologies: Works by Jamaal al-Din Zarabozo (a massive 3-volume commentary in English), Shaykh Mokhtar Maghraoui, and Dr. Umar Faruq Abd-Allah provide western students with authentic access to the classical heritage.
6. Recommended Three-Phase Study Roadmap
For serious students of sacred knowledge, educators suggest the following sequential reading curriculum:
- Phase 1: Foundations & Memorization (Months 1–3): Commit the Arabic text of the 42 hadiths to memory alongside an-Nawawi’s own brief commentary or the commentary of Shaykh al-'Uthaymeen. Focus on memorizing the core message and the primary Companion narrator.
- Phase 2: Jurisprudential Grounding (Months 4–6): Study the commentary of Ibn Daqiq al-Id. Pay close attention to grammatical particles, linguistic definitions, and how legal rulings are extracted from prophetic sentences.
- Phase 3: Ocean of Wisdom (Months 7–12): Immerse yourself in Ibn Rajab’s Jami' al-'Ulum wal-Hikam. Read each chapter slowly with a notebook, recording the sayings of the early Salaf, meditating on the ascetic traditions, and reflecting upon practical heart purification.
Conclusion
The great commentaries on Imam an-Nawawi's Forty are not mere historical relics; they are luminous lanterns that guide the human intellect through the complexities of life. By studying these classical treasures, a believer moves beyond the surface of prophetic words into the profound depths of divine wisdom, understanding how to apply the eternal Sunnah with wisdom, compassion, and unwavering fidelity.
