Introduction

Sahih Muslim is the second most highly authenticated collection of hadith in the Islamic tradition and, alongside Sahih al-Bukhari, forms the pair known as the Two Sahihs (al-Sahihayn). Its author, Imam Muslim ibn al-Hajjaj al-Qushayri al-Naysaburi, was born in Nishapur around 204 AH (820 CE) and dedicated his life to the sciences of hadith. He traveled to the Hijaz, Iraq, Syria, and Egypt in pursuit of narrations, sitting with leading scholars of his era including Imam Ahmad ibn Hanbal, Yahya ibn Ma'in, and — most significantly — Imam al-Bukhari himself, whose influence on Muslim's critical methodology was profound.

Imam Muslim selected the hadiths of his Sahih from a body of approximately 300,000 narrations he had gathered. The resulting collection contains around 7,500 hadiths with complete chains — roughly 3,033 without repetitions — chosen on criteria of rigorous authentication. Like al-Bukhari, Muslim required that narrators be trustworthy, have sound memory, and that their chains be continuous. However, Muslim's authentication approach differed subtly: he did not insist on demonstrated meeting between consecutive narrators in the chain as a strict condition, accepting established contemporaneity as sufficient. This methodological distinction is the basis of the classical debate between the two Sahihs, with most scholars viewing al-Bukhari's standard as marginally more demanding while affirming the full authenticity of Sahih Muslim.

What sets Sahih Muslim apart in the view of many scholars is its organizational superiority. Muslim grouped all narrations on a single topic together within one chapter, avoiding the repetition across different sections that characterizes al-Bukhari's method. This makes Sahih Muslim particularly useful for legal and thematic research: a reader seeking all narrations on a given matter of worship or ethics can find them assembled in one place. Muslim wrote a significant muqaddimah (introduction) to his work — a technical treatise on hadith methodology — which itself became an important early text in the science of hadith criticism ('ulūm al-hadith).

The collection covers the full range of Islamic practice and belief: the declaration of faith, prayer, purification, fasting, pilgrimage, zakah, oaths, jihad, transactions, marriage, hunting, food, dress, etiquette, the Day of Judgment, and the merits of the Companions. The hadiths on faith (iman) and divine decree (qadar) in the opening sections are among the most frequently cited in works of Islamic theology, as they convey foundational matters of 'aqeedah with chains that Muslim considered the soundest available.

The most widely studied commentary on Sahih Muslim is al-Minhaj by Imam Yahya ibn Sharaf al-Nawawi (died 676 AH), a work that combines hadith explanation with Shafi'i jurisprudence and remains in use today in traditional Islamic institutions. Other notable commentaries include those by al-Qadi 'Iyad and al-Suyuti.
