Etymology

Sunnah (Arabic: سنة) means well-trodden path, customary practice, or example[1]. In Islamic vocabulary it refers especially to the example of the Prophet Muhammad: his sayings, actions, approvals, and silences[2]. The term is also used more broadly for the way of the earliest Muslim community.

A common misunderstanding

sunnah is closely linked to hadith but not identical to any one report.

In Practice

The Sunnah is the second source of authority in Islam after the Quran[2]. Where the Quran is the direct word of God revealed through Muhammad, the Sunnah is the prophetic example that interprets and applies the Quran in practice. Together they form the foundation of Islamic law (sharia) and Islamic life.

The Sunnah is preserved primarily through hadith: reports about what the Prophet said, did, and approved. Hadith were collected, evaluated for authenticity, and compiled into major collections in the 8th and 9th centuries[3]. The two most authoritative Sunni hadith collections are Sahih al-Bukhari and Sahih Muslim, followed by the four other major collections (Abu Dawud, Tirmidhi, Nasa'i, Ibn Majah)[3]. Shia Islam has its own major hadith collections including Al-Kafi.

Following the Sunnah in daily life shapes much of Islamic practice: how to perform prayer, how to eat, how to greet others, how to dress modestly, how to conduct business, how to treat family[3]. The principle of bid'ah (innovation in religious matters, generally treated as undesirable) reflects the strong orientation toward prophetic example.

Sunni and Shia Islam differ in some aspects of the Sunnah they emphasize, particularly regarding succession after the Prophet and the role of the Imams in Shia tradition[2].

Scholarly Context

Hadith studies is a major field within Islamic scholarship and within academic religious studies. Wael Hallaq, Jonathan Brown, and others have produced important academic work on the formation and authentication of the hadith corpus[3]. Within Islamic tradition, the discipline of hadith criticism (with its categorization of reports as sahih, hasan, daif, and so on) developed extensively from early centuries onward.

Common Misconceptions

Misconception: The Sunnah is just oral tradition with no critical evaluation.

Correction: Classical Islamic scholarship developed extensive hadith criticism, evaluating chains of transmission and content[3]. The discipline produced significant works of scholarship distinguishing reliable from unreliable reports.

Misconception: All hadith are equally authoritative.

Correction: Hadith are graded by classical Islamic scholarship based on chains of transmission and other criteria. The strongest are sahih (sound), with descending grades of reliability[3]. Authoritative use of hadith depends on this grading.
