"I came to At-Ta'if and entered upon Anbasah bin Abi Sufyan when he was dying. I saw that he was afraid so I said: 'You will be fine.' He said: 'My sister Umm Habibah told me that the Messenger of Allah ﷺ said: Whoever prays twelve rak'ahs by day or by night, Allah, the Mighty and Sublime, will build for him a house in Paradise.'" (Using translation from Nasāʾī 1799)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ صَلَّى اثْنَتَيْ عَشْرَةَ رَكْعَةً نَافِلَةً بِالنَّهَارِ أَوْ بِاللَّيْلِ بُنِيَ لَهُ بَيْتٌ فِي الْجَنَّةِ»
