Narrated by:Umm Habibah said
It was narrated that Umm Habibah said:"Whoever prays twelve rak'ahs during the night and day apart from the prescribed prayers, a house will be built for him in Paradise."
أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا يَعْلَى، قَالَ حَدَّثَنَا إِسْمَاعِيلُ، عَنِ الْمُسَيَّبِ بْنِ رَافِعٍ، عَنْ عَنْبَسَةَ بْنِ أَبِي سُفْيَانَ، عَنْ أُمِّ حَبِيبَةَ، قَالَتْ مَنْ صَلَّى فِي اللَّيْلِ وَالنَّهَارِ ثِنْتَىْ عَشْرَةَ رَكْعَةً سِوَى الْمَكْتُوبَةِ بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ .
