Optional prayer surely has great value and many positive effects, however there are matters we need to pay attention to in that many Muslims do not give this prayer its full rights in terms of importance as well as being protective over how it is performed. You will find that many people leave off extra prayer, because they are too occupied or they are uninformed as to the lawfulness and its importance, and what comes with it by way of reward and blessing. Because of this I saw the need to prepare this booklet, which deals mainly with supererogatory prayer, which has been confirmed, by the actions of the Prophet ( صلی الله علیه وآلیه وسلم ) by his words and actions.
