question #3 Sahih Muslim 728a, Book 6, Hadith 124 : What are the benefits of maintaining regular voluntary prayers as mentioned in Islamic tradition?

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 (ﷺ). Some of the other narrators said the same words: I have never abandoned (observing them) since I heard (from so and so).
