أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمٍ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ مَكِّيٍّ، وَحِبَّانُ، قَالاَ حَدَّثَنَا عَبْدُ اللَّهِ، عَنْ إِسْمَاعِيلَ، عَنِ الْمُسَيَّبِ بْنِ رَافِعٍ، عَنْ أُمِّ حَبِيبَةَ، قَالَتْ مَنْ صَلَّى فِي يَوْمٍ وَلَيْلَةٍ ثِنْتَىْ عَشْرَةَ رَكْعَةً سِوَى الْمَكْتُوبَةِ بَنَى اللَّهُ عَزَّ وَجَلَّ لَهُ بَيْتًا فِي الْجَنَّةِ . لَمْ يَرْفَعْهُ حُصَيْنٌ وَأَدْخَلَ بَيْنَ عَنْبَسَةَ وَبَيْنَ الْمُسَيَّبِ ذَكْوَانَ .
It was narrated that Umm Habibah said: "Whoever prays twelve rak'ahs during the night and day apart from the prescribed prayers, Allah (SWT), the Mighty and Sublime, will build for him a house in Paradise."
