Sunan an-Nasai
أَخْبَرَنِي أَيُّوبُ بْنُ مُحَمَّدٍ، قَالَ أَنْبَأَنَا مُعَمَّرُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا زَيْدُ بْنُ حِبَّانَ، عَنِ ابْنِ جُرَيْجٍ، عَنْ عَطَاءٍ، عَنْ عَنْبَسَةَ بْنِ أَبِي سُفْيَانَ، عَنْ أُمِّ حَبِيبَةَ، قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ صَلَّى فِي يَوْمٍ ثِنْتَىْ عَشْرَةَ رَكْعَةً بَنَى اللَّهُ عَزَّ وَجَلَّ لَهُ بَيْتًا فِي الْجَنَّةِ " . قَالَ أَبُو عَبْدِ الرَّحْمَنِ عَطَاءٌ لَمْ يَسْمَعْهُ مِنْ عَنْبَسَةَ .
It was narrated from 'Ata from Anbasah bin Abi Sufyan, that Umm Habibah said: "I heard the Messenger of Allah (ﷺ) say: 'Whoever prays twelve rak'ahs a day, Allah (SWT), the Mighty and Sublime, will build for him a house in Paradise.'"
