The Salafi movement or Salafism (Arabic: السلفية, romanized: as-Salafiyya) is a fundamentalist revival movement within Sunni Islam, originating in the late 19th century and influential in the Islamic world to this day. The name "Salafiyyah" is a self-designation, claiming a return to the traditions of the predecessors (salaf), the first three generations of Muslims (the Islamic prophet Muhammad and the Sahabah [his companions], then the Tabi'in, and the third generation, the Tabi' al-Tabi'in), who are believed to exemplify the pure form of Islam. In practice, Salafis claim that they rely on the Qur'an, the Sunnah and the Ijma (consensus) of the salaf, giving these writings precedence over what they claim as "later religious interpretations". The Salafi movement aimed to achieve a renewal of Muslim life, and had a major influence on many Muslim thinkers and movements across the Islamic world.
Salafi Muslims oppose bid'ah (religious innovation) and support the implementation of sharia (Islamic law). In its approach to politics, the Salafi movement is sometimes divided by Western academics and journalists into three categories: the largest group being the purists (or quietists), who avoid politics; the second largest group being the activists (or Islamists), who maintain regular involvement in politics; and the third group being the jihadists, who form a minority and advocate armed struggle to restore early Islamic practice. In legal matters, Salafis advocate ijtihad (independent reasoning) and oppose taqlid (blind faith) to the four schools (madhahib) of Islamic jurisprudence.
