If any Muslim servant (of Allah) prays for the sake of Allah twelve rak'ahs (of Sunan) every day, over and above the obligatory ones, Allah will build for him a house in Paradise, or a house will be built for him in Paradise; and I have not abandoned observing them after (hearing it from the Messenger of Allah). (So said also 'Amr and Nu'man.)  

عَنْ أُمِّ حَبِيبَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا مِنْ عَبْدٍ مُسْلِمٍ يُصَلِّي لِلَّهِ كُلَّ يَوْمٍ ثِنْتَىْ عَشْرَةَ رَكْعَةً تَطَوُّعًا غَيْرَ فَرِيضَةٍ إِلاَّ بَنَى اللَّهُ لَهُ بَيْتًا فِي الْجَنَّةِ أَوْ إِلاَّ بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ قَالَتْ أُمُّ حَبِيبَةَ فَمَا بَرِحْتُ أُصَلِّيهِنَّ بَعْدُ وَقَالَ عَمْرٌو مَا بَرِحْتُ أُصَلِّيهِنَّ بَعْدُ وَقَالَ النُّعْمَانُ مِثْلَ ذَلِكَ  

[Machine] The Messenger of Allah ﷺ said, "There is no Muslim servant who performs ablution, perfects it, and then prays to Allah every day twelve voluntary rak'ahs except that a house is built for him in Paradise." Umm Habibah said, "I have continued praying them after that." Anbasah said, "I have continued praying them after that." 'Amr ibn Aws said, "I have continued praying them." Nu'man said, "And I hardly ever omit them." Ibn Ja'far reported from Anbasah bin Abi Sufyan from Umm Habibah, the wife of the Prophet ﷺ , that she heard the Prophet ﷺ saying, "There is no Muslim servant who prays to Allah every day twelve voluntary rak'ahs, other than the obligatory ones, except that his likeness is such as that."  

قَالَ رَسُولُ اللهِ ﷺ مَا مِنْ عَبْدٍ مُسْلِمٍ تَوَضَّأَ فَأَسْبَغَ الْوُضُوءَ ثُمَّ صَلَّى لِلَّهِ ﷻ كُلَّ يَوْمٍ ثِنْتَيْ عَشْرَةَ رَكْعَةً إِلَّا بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ قَالَتْ أُمُّ حَبِيبَةَ فَمَا زِلْتُ أُصَلِّيهِنَّ بَعْدُ وقَالَ عَنْبَسَةُ فَمَا زِلْتُ أُصَلِّيهِنَّ بَعْدُ وقَالَ عَمْرُو بْنُ أَوْسٍ فَمَا زِلْتُ أُصَلِّيهِنَّ قَالَ النُّعْمَانُ وَأَنَا لَا أَكَادُ أَدَعُهُنَّ قَالَ ابْنُ جَعْفَرٍ عَنْ عَنْبَسَةَ بْنِ أَبِي سُفْيَانَ عَنْ أُمِّ حَبِيبَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا سَمِعَتِ النَّبِيَّ ﷺ يَقُولُ مَا مِنْ عَبْدٍ مُسْلِمٍ يُصَلِّي لِلَّهِ ﷻ كُلَّ يَوْمٍ ثِنْتَيْ عَشْرَةَ رَكْعَةً تَطَوُّعًا غَيْرَ فَرِيضَةٍ فَذَكَرَ نَحْوَهُ  

[Machine] From Umm Habibah, the wife of the Prophet ﷺ , she narrated that she heard the Prophet ﷺ say, "There is no Muslim servant who prays twelve voluntary Rak'ahs every day, other than the obligatory prayers, except that Allah will build a house for him in Paradise or a palace in Paradise." Umm Habibah said, "I have never ceased praying them after I heard this." 'Amr ibn Salamah said the same, and Nu'man said the same.  

عَنْ أُمِّ حَبِيبَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا سَمِعَتِ النَّبِيَّ ﷺ يَقُولُ «مَا مِنْ عَبْدٍ مُسْلِمٍ يُصَلِّي كُلَّ يَوْمٍ ثِنْتَيْ عَشْرَةَ رَكْعَةً تَطَوُّعًا غَيْرَ الْفَرِيضَةِ إِلَّا لَهُ بَيْتٌ فِي الْجَنَّةِ أَوْ بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ » قَالَتْ أُمُّ حَبِيبَةَ فمَا بَرِحْتُ أُصَلِّيهِنَّ بَعْدُ وَقَالَ عَمْرٌو مِثْلَهُ وَقَالَ النُّعْمَانُ مِثْلَهُ
