Sunan al-Kubra by Imam al-Nasa’i is one of the major classical collections of ḥadīth in Sunni Islam. Compiled by the renowned scholar Ahmad ibn Shuʿayb al-Nasa’i (d. 303 AH/915 CE), the work contains thousands of narrations covering Islamic belief, worship, law, ethics, and daily life. It is distinguished by Imam al-Nasa’i’s careful methodology and strong emphasis on authentic narrations.
The collection was later abridged by the author himself into Al-Mujtaba, commonly known as Sunan al-Nasa’i, which became one of the six canonical ḥadīth books (Kutub al-Sittah). Sunan al-Kubra remains an important resource for scholars due to its broader range of narrations, detailed chapter arrangement, and inclusion of variant chains and reports useful in ḥadīth criticism and Islamic jurisprudence.
