If you aspire to a house at paradise, there is a way to that through praying twelve raka`ah every day other than the obligatory prayer. Umm Habiba (the wife of the Holy Prophet) reported Allah's Messenger (PBUH) 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 (PBUH). Some of the other narrators said the same words: I have never abandoned (observing them) since I heard (from so and so). Muslim.

It is definite and distributed throughout the day where An-Nasaai related, ranked sahih by Al-Albani, on the authority of Aishah who said: "The Messenger of Allah (PBUH) said: 'Whoever persists in praying twelve rak'ahs each day and night will enter Paradise: Four before Zuhr and two after, two rak'ahs after Maghrib, two rak'ahs after Isha' and two rak'ahs before Fajr.'"

This indicates that persistence on observing these twelve raka`ah leads to a house paradise which made narrators adhere to them until the end of their lives.
