What did the Holy Prophet (peace be upon him) say about anyone who prays twelve rak'ahs a day and night?
 Umm Habiba (the wife of the Holy Prophet) reported Allah's Messenger (may peace be upon him) as saying:                      A house will be built in Paradise, for anyone who prays in a day and a night twelve rak'ahs; and she added: I have never abandoned (observing them) since I heard it from the Messenger of Allah (may peace be upon him). Some of the other narrators said the same words: I have never abandoned (observing them) since I heard (from so and so).
