أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ أَنْبَأَنَا زُهَيْرٌ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْمُسَيَّبِ بْنِ رَافِعٍ، عَنْ عَنْبَسَةَ، أَخِي أُمِّ حَبِيبَةَ عَنْ أُمِّ حَبِيبَةَ، قَالَتْ 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 ‏.‏
