What Islamic Scholars and Reviewers Say About “Purification of the Heart”

Recognition of the Translator: Hamza Yusuf has been described by The Guardian as “arguably the west’s most influential Islamic scholar” and The New Yorker reported he is “perhaps the most influential Islamic scholar in the Western world.” He was also ranked as “the Western world’s most influential Islamic scholar” by The 500 Most Influential Muslims publication.

Scholarly Endorsements: The book deals with the Islamic science of tasawwuf, which scholars note is more meaningfully interpreted as ‘purification’ rather than simply sufism. Great Islamic scholar Sidi Ahmad Zarruq defined Sufism as “sincerity in turning to Allah,” which aligns with the book’s core message.

Academic and Practical Value: Reviewers note the book is well presented, easy to read, and sufficiently accessible in its language, making it beneficial even for non-Muslims. One detailed review described it as “easy to follow, well-structured and profound in its advice,” with Hamza Yusuf adding insightful commentary that relates to modern experiences.

Integration of Classical Scholarship: The book draws upon the teachings of major scholars like Imam al-Ghazali, an 11th-century master of the science of purification. Each chapter contains relevant references from the Qur’an and Hadith that provide practical solutions to spiritual tribulations.

Practical Approach: Reviewers emphasize that the book requires deep reflection and recommend focusing on one or two chapters at a time to encourage applying changes to one’s life, noting that purification is a lifelong process, not a destination.

The book has been widely adopted in Islamic studies programs and is considered a foundational text for understanding spiritual purification in the Islamic tradition.

Insights About the Poem “Matharat al-Qulub”

Origin and Purpose

The poem literally translates to “Purification of the Hearts” and is described as a treatise on the “alchemy of the hearts”—essentially a manual on how to transform the heart. Shaykh Muhammad Mawlud wrote this poem because he observed the prevalence of diseased hearts in his time, noting that students of religion were spending their time learning abstract sciences that people were not really in need of, while neglecting the sciences that pertain to what people are accountable for in the next life—namely, the spiritual condition of the heart.

The Author’s Background

Muhammad Mawlud was born in Mauritania around 1260 Hijra/1844 CE into a family of scholars descended from Ja’far ibn Abi Talib, the cousin of Prophet Muhammad. He authored a total of 70 works including books, poems and commentaries, specifically focusing on spirituality and the Arabic language, before passing away in 1323 H/1905 CE.

Literary Form and Structure

The poem begins with the verses: “I begin by starting with the heart of beginnings, for it is the highest and noblest of beginnings. Have courtesy with God, the High and the Majestic, by practicing modesty and humility—”

Imam Mawlud begins with a play on words in Arabic where “bad’u” (beginning) is reversed to create “adab” (courtesy), establishing courtesy as the portal to the purification of the heart.

Mauritanian Scholarly Tradition

Despite Mauritania being a desert country with harsh environmental conditions, the Mauritanians established a sophisticated system of preserving the sacred sciences of Islam through specific clans called zawāya that made scholarship their primary focus and passed knowledge to each successive generation through traditional Islamic universities known as maḥḍaras.

The Poem’s Unique Approach

This work is distinctive because the main text is poetry, which reflects how poetry remains a massive part of certain Eastern cultures, though somewhat lost and forgotten in the West. The poem was written in the 19th century and recently received its first-ever complete English translation by a formerly incarcerated student who spent years producing an English commentary while studying the faith.

The poem represents a masterful integration of Islamic spirituality, psychology, and practical guidance, all conveyed through the powerful medium of classical Arabic poetry.
