Muhammad Rashid Rida was a prominent early Salafist Sunni Islamic scholar, reformer, theologian, and Islamic revivalist. As a Salafi scholar who called for the revival of hadith studies and a theoretician of an Islamic state, Riḍā condemned the rising currents of secularism and nationalism across the Islamic world following the abolition of the Ottoman sultanate and championed a global pan-Islamist program aimed at re-establishing an Islamic caliphate.

The Salafi movement or Salafism is a revival movement within Sunni Islam, which was formed as a socio-religious movement during the late 19th century and has remained influential in the Islamic world for over a century. The name "Salafiyya" refers to advocacy of a return to the traditions of the "pious predecessors", the first three generations of Muslims, who are believed to exemplify the pure form of Islam. In practice, Salafis maintain that Muslims ought to rely on the Qur'an, the Sunnah and the Ijma (consensus) of the salaf, giving these writings precedence over 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.
