The Unique Features of Sunan Abi Dawud

The most significant feature of Sunan Abi Dawud is that it contains only narrations related to legal rulings and matters of jurisprudence. Before Imam Abu Dawud, it was not customary to compile books in this specific style. Rather, earlier works typically included narrations on rulings, tafsir (exegesis), stories, historical reports, sermons, and asceticism—meaning they were comprehensive works or Musnads. As mentioned by the Imam himself in his “Risalah Makkiyyah,” he chose a unique path. Due to this unique characteristic, his book became a central point of attention for scholars and Imams of hadith. As Imam Nawawi (رحمه الله) said:

“As for the pure collections of Sunan (legal traditions), no one before attempted to collect and complete them, nor were they able to extract them from within the lengthy hadith collections like Abu Dawud did. Hence, his book astonished the leading scholars of hadith and experts of tradition, who traveled far and wide to obtain it.” (Tazhib al-Asma’ wal-Lughat, vol. 2, p. 227)

When it comes to Sunan—that is, hadiths concerning legal rulings—no one else intended or managed to comprehensively compile and summarize them from lengthy narrations as Abu Dawud did. Therefore, among the scholars of hadith and experts in Islamic tradition, this book is considered an extraordinary compilation for which travel and journeys have consistently been undertaken.

2- The Rich Collection of Legal Hadiths

The vast collection of legal hadiths in this book is unmatched by any of the other canonical collections. Hafiz Abu Ja‘far Ibn al-Zubayr al-Gharnati (d. 708 AH), while listing the features of the six major hadith books (Sihah Sittah), writes: “What Abu Dawud has done in gathering and encompassing hadiths of rulings has not been done by others.” (Tazhib al-Asma’ wal-Lughat, vol. 2, p. 227)

For this reason, this book has always been a reliable and authoritative source for jurists and mujtahids (independent legal scholars).

3- Practical Usage by the Great Jurists

Just like Jami‘ al-Tirmidhi, most of the narrations in Sunan Abi Dawud were accepted and practiced by leading jurists, the Tabi‘in, and their followers. Particularly, the book holds foundational value for the schools and methodologies of scholars like Imam Malik (رحمه الله), Imam Sufyan al-Thawri (رحمه الله), Imam al-Awza‘i (رحمه الله), and other hadith experts and jurists. Al-Khattabi said this book serves as a decisive reference and proof in matters of juristic disagreement:

“It is relied upon by the scholars of Iraq, Egypt, the Maghreb, and many other regions of the world.” (Ma‘alim al-Sunan, vol. 1, p. 6)

4- Emphasis on Authentic and Connected Chains

In the book of Sunan, special attention has been given to hadiths that are authentic, strong, connected, and elevated (marfu‘). To assess the level of authenticity, one must note that Imam Abu Dawud collected 500,000 hadiths and selected only 4,800 from them, presenting them as a comprehensive collection. According to his own statement, he made every effort to select the most authentic narrations based on his knowledge and conviction, always preferring narrations with the strongest chains.

Al-Khattabi said: “It has been narrated to us that Abu Dawud said: I have not included in my book any hadith that the scholars have unanimously agreed to abandon.”

5- Compilation of Multiple Chains and Wordings

Another feature is that Imam Abu Dawud often compiles multiple chains (isnads) and variations of wording (matn) for a single narration and then explains each chain and variation separately.

6- Avoidance of Repetition

No hadith book is entirely free from repetition, but Imam Abu Dawud has minimized it wherever possible, often omitting repeated chains and summarizing lengthy hadiths. He only repeats when a narration contains a unique ruling or when a new legal deduction is derived.

7- Order and Composition

He maintained both comprehensiveness and an excellent sense of order and composition in his work. Al-Khattabi remarked: “Indeed, the structure of Abu Dawud’s book is the best.”

8- Clarification of Narrators

Where necessary, he provided clarifications about the narrators’ names, titles, and lineage. He also discussed their reliability or unreliability (al-jarh wa al-ta‘dil), and clearly pointed out the soundness or weakness of their narrations.

9- Preference for Well-Known Narrations

Imam Abu Dawud focused on collecting well-known and commonly practiced narrations, avoiding rare and unusual reports.

10- Inclusion of a Thulathi Hadith

The collection also includes a rare narration with only three transmitters in the chain (thulathi).

May blessings and peace be upon our Prophet Muhammad, his family, companions, and all those who follow him with excellence until the Day of Judgment.
