It is narrated from Lady Umm Habibah (may Allah be pleased with her), the wife of the Noble Prophet (peace and blessings be upon him), that she heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever among the Muslim servants prays twelve units of Sunnah prayer other than the obligatory prayers, for him there is a house in Paradise," or he said: "A house is built for him in Paradise." Lady Umm Habibah (may Allah be pleased with her) said: For this reason, I have continued to perform these Sunnah prayers regularly. Amr bin Aws and Nu'man bin Salim also said the same, meaning that since they heard this, they have never abandoned these Sunnah prayers.
