The Mawaani’ (preventers) in consideration of the performance and request are divided into two categories:

1 – A Maani’ that is preventative of the Talab (request) and prevents the performance and this is like the loss of the ‘Aql (mind) due to sleep or insanity. That is because it prevents the request of prayer, fasting and trade amongst other matters related to the Ahkaam. At the same time, it prevents its performance and so this kind represents a preventer (Maani’) from the original Takleefiy Talab (request).

2 – A Maani’ that prevents the Talab but does not prevent the performance and this is like being female in respect to the Jumu’ah prayer. That is because being female is a preventer of the request of Salaat ul-Jumu’ah however if the woman was to perform the Salaah it would be valid for her because the Maani’ is preventative of the Talab but not the Adaa’ (the request but not the performance). Similarly, Safar (travelling) is a Maani’ for the Talab (request) of fasting (As-Sawm) or from completing the four Rak’ah of the four Rak’ah prayers. However, if the Musaafir (traveller) was to fast or pray four Rak’ah without shortening, that would be permitted for him because the Maani’ represents a preventer (Maani’) from the Talab and not the ‘Adaa (performance).

Similarly, all of the causes of Rukhas (plural of Rukhsah meaning special permission or licence to leave an action) represent Mawaani’ (preventers) from the Talab (request) and not from the performance.
