Shaykh Muhammad Ibn Abdil Wahhab Ibn Sulayman At-Tamimi Rahimahullah was a prominent Islamic scholar born in Najd, Arabia in 1703. He was a key figure in the Islamic revivalist movement of the 18th century, known as the "Wahhabi movement." He called for a return to the fundamental principles of Islam, rejecting the popular practices and beliefs that had become widespread in his time. He is known for his teachings on Tawhid (the oneness of God), the importance of purifying one's beliefs and actions, and the need to reject all forms of shirk (associating partners with God). His teachings continue to have a significant influence on Islamic thought and practice around the world.
