Umm Habibah reported that she heard the Prophet ﷺ say, "There is no Muslim servant who prays twelve rakat each day for Allah voluntarily, apart from the obligatory prayers, but that a house will be built for him in Paradise," or, "but that Allah
will build for him a house in Paradise because of them."Umm Habibah then said, "I have never stopped praying them since."Amr said, "I have never stopped praying them since."And Numan said the same.
حدثنا محمد بن جعفر قال حدثنا شعبة عن النعمان بن سالم عن عمرو بن أوس عن عنبسة بن أبي سفيان
أنها سمعت النبي ﷺ يقول ما من عبد مسلم يصلي لله عز وجل كل يوم ثنتي عشرة ركعة تطوعا غير فريضة إلا بني له بيت في الجنة أو بنى الله عز وجل له بهن بيتا في الجنة فقالت أم حبيبة فما برحت أصليهن بعد وقال عمرو ما برحت أصليهن بعد وقال النعمان مثل ذلك
Its isnad is sahih. Numan bin Salim is Taifi, and he is trustworthy, his hadith is found in Muslim and the four (Sunan collections). Amr bin Aws is Thaqafi Taifi, a senior member of the generation after the Companions among the most excellent, and his hadith is found in the Jamaah (the six major collections). This hadith is like the one before it.
