It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that for six months, it was the practice of the Noble Prophet (peace and blessings be upon him) that when he would pass by the house of Sayyidah Fatimah (may Allah be pleased with her) at the time of Fajr prayer, he would say: O people of the household! Perform the prayer. Verily, Allah only intends to remove all impurity from you (the people of the household) and to purify you completely.
