Ibn Taymiyyah said: "This (enjoining good and forbidding evil) is a duty that the entire Ummah is obliged to fulfil. It is what the Ulama know as an obligation of collective responsibility, if a group in society undertook to discharge it, the other members of this society are absolved from it. The entire Ummah is commissioned to undertake it, but if a group therein was responsible for discharging it, the rest of society is no longer obliged to undertake it."

The Life, Teachings and Influence of Muhammad ibn Abdul-Wahhaab: This book is not one with a political agenda. It is meant neither to support nor to critique any contemporary regimes or policies. Indeed, the driving force behind this work is much greater and more important than that. It has to do with, first, the religion of Islam as preached by the Prophet (peace and blessings of Allah be upon him) himself and, second, with the honor and rights of an individual Muslim, Muhammad ibn Abdul-Wahhaab.
