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 commisioned to undertake it, but if a group therin was responsible for discharging it, the rest of society is no longer obliged to undertake it.?
