Imam Muslim ibn al-Hajjaj

Imam Muslim ibn al-Hajjaj al-Qushayri an-Naysaburi (206-261 AH / 821-875 CE) was one of the greatest hadith scholars in Islamic history, whose Sahih stands as one of the two most authoritative hadith collections in the Sunni tradition. His full name was Abu al-Husayn Muslim ibn al-Hajjaj ibn Muslim al-Qushayri, and he was born in Nishapur (Naysabur) in Khorasan, one of the great intellectual centers of the Islamic East.

He began his hadith studies at a young age and traveled widely across the Muslim world, studying under the leading scholars of the Hejaz, Iraq, Syria, and Egypt. His most important teacher was Imam al-Bukhari, whom he revered profoundly — it is reported that he kissed al-Bukhari's forehead in admiration and declared him the master of the masters of hadith. Among his other major teachers were Yahya ibn Yahya an-Naysaburi, Ishaq ibn Rahuyah, Ahmad ibn Hanbal, and Abd ar-Razzaq as-Sanani.

Muslim examined approximately 300,000 narrations and selected around 7,500 distinct hadiths for his Sahih. His methodology required connected chains of trustworthy narrators who had actually met one another, and he was exceptionally meticulous about preserving the exact wording of each narration. His distinctive organizational method gathers all variant wordings of a hadith under a single chapter heading, making it easier for scholars to compare chains and assess textual variations. The famous introduction to his Sahih contains important discussions about the principles of hadith authentication that influenced all later scholars of the science of hadith.

His students included major scholars such as Ibrahim ibn Muhammad ibn Sufyan, who was chiefly responsible for transmitting the Sahih to the world. Muslim spent his career in Nishapur teaching, writing, and refining his monumental work.

He died in Nishapur in 261 AH (875 CE). His Sahih, together with that of al-Bukhari, forms the most authoritative core of the hadith canon. The landmark commentary by Imam an-Nawawi on Sahih Muslim remains among the most widely studied works of hadith explanation in Islamic seminaries worldwide and has shaped how generations of scholars understand and apply these narrations.
