The opening as it read in 2005

Muhammad ibn Abd al-Wahhab al-Tamimi (b. 1703 'Uyyainah العوينة, Najd , Arabia – d. 1792 al-Dir'yah ) is the most famous scholar of the fundamentalist movement within Islam known as the Wahhabi movement and after whom the movement is named. He considered this movement an effort to purify Islam by returning all Muslims to what he believed were the original principles of Islam, as typified by the as-salaf as-saliheen , the earliest converts to Islam, by rejecting what he regarded as corruptions introduced by Bida (innovation, reformation) and Shirk (idolatry) . He also revived interest in the works of Ibn Taymiya ; those who follow the "revival" that he advocated are often referred to as Salafis .1
