According to a study by Michael Cook, based on "Wahhabi writings and rulers' decrees" the role of commanding good and forbidding wrong developed a prominent place during the second Saudi emirate, and the first "documented instance of a formal committee to enforces the duty dates to 1926", when the official Saudi newspaper in Mecca published the news of its establishment. "One ruler orders his emirs to seek out people who gather together to smoke tobacco ... scholars and emirs should keep a check on the people of their towns with regard to prayer and religious instruction." Performance of hajj "is likewise to be monitored."Cook, Forbidding Wrong, 2003, p.126
