Introduction

Yūsuf al-Qaraḍāwī (1926–2022) was one of the most widely read and debated Islamic scholars of the modern era. Born in Egypt, he studied at Al-Azhar under some of the foremost scholars of the twentieth century and went on to become a prolific author, lecturer, and jurist whose works reached Muslim communities across the globe. His career unfolded during a period of intense ideological contestation within the Muslim world, as various reformist and rationalist currents questioned the binding authority of the prophetic Sunnah alongside the Qurʾān. It was in direct response to this intellectual pressure that al-Qaraḍāwī produced this defense of the Sunnah's indispensable role in Islamic life and law. The work reflects his characteristic methodology: grounding argument in classical scholarship while addressing the concerns of educated modern Muslims who have encountered skeptical critiques of hadith literature.

The central contention of this book is that the Sunnah, the recorded words, actions, and tacit approvals of the Prophet Muḥammad (ṣallā Allāhu ʿalayhi wa-sallam), constitutes an authoritative and binding source of Islamic guidance alongside the Qurʾān, and that this status is established by the Qurʾān itself, by the practice of the Companions, and by the unbroken consensus of Muslim scholars across fourteen centuries. Al-Qaraḍāwī addresses the major objections raised by those who seek to limit the Sunnah's authority or dismiss it as a later fabrication. He examines the historical process by which hadith were preserved, transmitted, and critically evaluated by the scholars of the classical period, and he explains the rigorous science of hadith criticism (ʿilm al-rijāl and ʿilm al-jarḥ wa-l-taʿdīl) that Islamic civilization developed precisely to guard against forgery and error. The book proceeds through argument, not mere assertion, and engages the intellectual objections it addresses on their own terms.

The work has circulated widely in Arabic and in translation since its first publication, becoming an important resource for Muslim scholars, students, and educated laypeople who seek a coherent rebuttal to Qurʾān-only tendencies and other heterodox critiques of the hadith sciences. Its significance lies in its accessibility: al-Qaraḍāwī writes for the intelligent non-specialist as much as for the trained scholar, and his prose is clear and rhetorically forceful without sacrificing substantive argument. The book has been used in Islamic institutes as a companion text to hadith science curricula, and it remains relevant as similar debates continue in online and academic settings. Western-educated Muslims in particular have found it a useful bridge between the classical scholarly tradition and the questions they encounter in secular intellectual environments.

Readers approaching this work are advised to engage it with both an open mind and a critical one. Al-Qaraḍāwī is making a case, and readers will gain the most by tracking the structure of his argument, noting the evidence he marshals, and considering the classical sources he cites. Those who come with prior knowledge of hadith sciences will find the work confirms and extends their understanding; those who are new to the subject will find it a solid introduction to why Muslims regard the Sunnah as divinely guided guidance alongside the Qurʾān. The book ultimately invites the reader to appreciate the intellectual depth of the Islamic tradition's approach to preserving and verifying prophetic knowledge, and to understand why that tradition has regarded the Sunnah as inseparable from a complete understanding of Islamic practice and belief.
