Prophet Muhammad (peace be upon him) predicted that a time would come when people would deliberately leave the Sunnah, and rely only on the Noble Quran. Both this authentic hadith and many verses of the Quran make it clear that to do so is delusional and misguided.

Allah Most High Said, “And whatever the Messenger has given you, take it; and what he has forbidden you, refrain from it.” [Al-Hashr (59):7]

The Prophet said, “I have not left out anything of which Allah, The Most High has Commanded you with except I have apprised you of it. Likewise, I have not left out anything of which Allah has Prohibited you from it, except I have apprised you of it…” [Al Bayhaqi, 7/76 & others]

Together with the Qur’an, the Sunnah is the pivotal foundation and primary source of the Islamic faith. Following both of them is mandated by Allah Himself and obligated upon Muslims to adhere and live accordingly. Muslim theology is established upon them and remains defective and incomplete should either be forsaken for they both explain and interpret each other.

During his time, Imam al-Suyuṭi felt a genuine need to pen this compelling book in confuting those who either rejected the Sunnah altogether or did not grant it the status and respect it deserves in the religion. He primarily compiled from the works of Imam Al-Bayhaqi elucidating the position of Imam Shafi’i, and firmly laid out the arguments supporting the Sunnah of the Prophet by outlining its critical importance, its authority, and implication to one’s life.

Salvation, therefore, lies in embracing the Sunnah fully, for indeed it is the key to facilitating our worldly lives and thereafter, unlocking the doors of Paradise, as Shadh ibn Yaḥya said perfectly, “There is no better way to Paradise than the way of those who have followed the Sunnah.”

The Sunnah and its Role in Islamic Legislation is a groundbreaking effort by Dr. Mustafa as-Siba’ee, for it has a completeness to it in two regards: first, the author manages to cover all topics related to the Sunnah—its status, its legislative force, the stages that led to its recording, just to mention a few—in a comprehensive and organized manner. Second, he presents the views of those that have attacked the Sunnah throughout history, detailing their arguments and then refuting them. Among those groups from the past were the Shi’aa and the Mu’tazilah; today, they are mainly the Orientalists and those that are influenced by them.

Sheikh as-Siba’ee takes us through the historical development of the Sunnah, from the early stages of revelation to the recording of the Sunnah during the era of the great Imams of Hadith. Throughout that account, he highlights the contributions of the scholars in preserving the Sunnah and cleansing it from fabrications and lies. Shaykh as-Siba’ee gives a clear account of the revolutionary methods and scholarly principles that were established in order to authenticate historical reports and narrations. The author shows us that the fruits of that endeavour were the preservation of the authentic Sunnah and the birth of the Hadith sciences.

This book has been a perennial source of knowledge for Arabic-speaking students of Islam, for its clarity, readability, and insightful research. New English-speaking students too have available to them this authoritative treatise on the Sunnah of our beloved Prophet Muhammad) may the peace and blessings of ALLAH be upon him).
