The Four Sunan Books

The Four Sunan Books (Part of the Six Canonical Collections)

While commonly referred to alongside the Two Sahihs (Sahih Al-Bukhari and Sahih Muslim), these collections focus primarily on legal rulings and include varied grades of authenticity:

• Sunan Abu Dawud: Compiled by Imam Abu Dawud, focusing heavily on legal (Fiqh) traditions.

• Jami' at-Tirmidhi: Compiled by Imam at-Tirmidhi, famous for classifying the authenticity level of each Hadith and detailing differences in legal jurisprudence.

• Sunan an-Nasa'i: Compiled by Imam an-Nasa'i, noted for having the strict criteria for narrator reliability among the four Sunan.

• Sunan Ibn Majah: Compiled by Imam Ibn Majah, completing the traditional six collections with supplementary traditions not found in the other five.

The exact composition dates for the four Sunan books are not recorded, as Islamic scholars during the Golden Age compiled, revised, and taught their collections over decades of travel and teaching. However, all four books were compiled during the 9th century CE (3rd century AH).

The timelines for when these books were authored and disseminated correspond to the lifetimes and active teaching periods of their compilers:

• Sunan Abu Dawud: Compiled roughly between 840–880 CE (approx. 225–265 AH). Imam Abu Dawud (d. 889 CE / 275 AH) spent decades selecting roughly 4,800 to 5,000 legal ahadith from a pool of 500,000. He famously presented a completed draft of his Sunan to his teacher, Imam Ahmad ibn Hanbal (d. 855 CE).

• Jami' at-Tirmidhi: Compiled roughly between 860–888 CE (approx. 245–275 AH). Imam at-Tirmidhi (d. 892 CE / 279 AH) spent over two decades traveling across Khurasan, Iraq, and the Hijaz collecting narrations before finalizing his collection, which he shared with scholars of Khurasan and Hijaz during his lifetime.

• Sunan an-Nasa'i: Compiled roughly between 870–910 CE (approx. 255–297 AH). Imam an-Nasa'i (d. 915 CE / 303 AH) first compiled a large collection called Al-Sunan al-Kubra. Later in his life, he edited and condensed it down to a more stringent, highly authentic version known as Al-Sunan al-Sughra (or Al-Mujtaba), which is the standard Sunan book known today.

• Sunan Ibn Majah: Compiled roughly between 860–880 CE (approx. 245–265 AH). After completing a 15-year study journey across the Middle East that began around 844 CE (230 AH), Imam Ibn Majah (d. 887 CE / 273 AH) returned to his hometown of Qazwin, where he dedicated his final decades to writing and dictating his Sunan.
