Hazrat Anas bin Malik (may Allah be pleased with him) narrates that when the Messenger of Allah (peace and blessings be upon him) would go out for the Fajr prayer in the morning, he would pass by the house of Hazrat Fatimah (may Allah be pleased with her) for six months and say: "O people of the house! It is time for prayer." Then he would say: "Indeed, Allah only desires to remove impurity from you, O people of the household, and to purify you completely."
