The Book Of Prayer: Salaat (Prayer) is one of the main obligations which Allah (subhanahu wa ta’ala) has ordained on His servants. It is the first act of worship decreed on the Muslim Nation (Ummah) by Allah (subhanahu wa ta’ala) and was ordained on the night of the Prophet’s (peace be upon him) ascension to the seven heavens. It is the second of the five pillars of Islam after the proclamation of the “Shahada” (the words of witness).

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."
