" مَنْ صَلَّى فِي يَوْمٍ ثِنْتَىْ عَشْرَةَ رَكْعَةً سِوَى الْفَرِيضَةِ بَنَى اللَّهُ لَهُ أَوْ بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ "
It was narrated that Umm Habibah said: "The Messenger of Allah (ﷺ) said: 'Whoever prays twelve rak'ahs in a day apart from the obligatory prayers, Allah (SWT) will build for him, or there will be built for him, a house in Paradise.'"
