Arabic (Original)
حَدَّثَنَا هُشَيْمٌ قَالَ أَخْبَرَنَا دَاوُدُ بْنُ أَبِي هِنْدٍ عَنِ النُّعْمَانِ بْنِ سَالِمٍ عَنْ عَنْبَسَةَ بْنِ أَبِي سُفْيَانَ قَالَ أَخْبَرَتْنِي أُمُّ حَبِيبَةَ بِنْتُ أَبِي سُفْيَانَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَقُولُ مَنْ صَلَّى فِي يَوْمٍ ثِنْتَيْ عَشْرَةَ رَكْعَةً تَطَوُّعًا غَيْرَ فَرِيضَةٍ بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ.
English Translation
Hushaym told us, he said Dawud ibn Abi Hind informed us, from al-Nu'man ibn Salim, from Anbasah ibn Abi Sufyan, who said: Umm Habibah bint Abi Sufyan informed me that the Messenger of Allah, peace and blessings be upon him, used to say, "Whoever prays twelve rak'ahs in a day, voluntary, other than the obligatory prayers, will have a house built for him in Paradise."
