It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) came to Sayyidah Fatimah (may Allah be pleased with her) with a slave whom he (peace and blessings be upon him) had given to Sayyidah Fatimah (may Allah be pleased with her) as a gift. Sayyidah Fatimah (may Allah be pleased with her) had on a garment; when she covered her head, her feet were left bare, and when she covered her feet, her head was left bare. When he (peace and blessings be upon him) saw this, he said: "There is no harm on you, for one is your father and the other is your slave."
