مَنْ صَلَّى فِي الْيَوْمِ وَاللَّيْلَةِ ثِنْتَىْ عَشْرَةَ رَكْعَةً سِوَى الْمَكْتُوبَةِ بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ أَرْبَعًا قَبْلَ الظُّهْرِ وَرَكْعَتَيْنِ بَعْدَهَا وَثِنْتَيْنِ قَبْلَ الْعَصْرِ وَثِنْتَيْنِ بَعْدَ الْمَغْرِبِ وَثِنْتَيْنِ قَبْلَ الْفَجْرِ .
It was narrated that Umm Habibah said: "Whoever prays twelve rak'ahs during the night and day other than the prescribed prayers, a house will be built for him in Paradise: four before Zuhr and two rak'ahs afterward, two before Asr, two after Maghrib and two before Fajr."
