On the authority of the Mother of the Believers, Umm Ḥabībah Ramlah bint Abī Sufyān (may Allah be pleased with her), who said: I heard the Messenger of Allah ﷺ say: "There is no Muslim servant who prays to Allah, the Exalted, twelve rakʿahs each day voluntarily, over and above the obligatory prayers, but that Allah builds for him a house in Paradise" — or: "but that a house is built for him in Paradise." Narrated by Muslim.
