As-Sunan al-Kubra

As-Sunan al-Kubra, (سنن الكبرى), is a hadith book collected by Imam Al-Nasa'i (214 – 303 AH), not to be confused with the same titled book by Imam Al-Bayhaqi.

Description
As-Sunan al-Kubra is the larger collection of the Sunan al-Nasa'i, having almost twelve thousand (12000) hadiths compared to the almost six thousand (6000) hadiths in the summarised version. The shorter collection is considered the next most authentic book of hadith (narrations of Muhammad) after the Sahihain (Sahih al-Bukhari & Sahih Muslim) within the six books, by most scholars of hadith.
