It is narrated from Hazrat Anas (may Allah be pleased with him) that once Hazrat Fatimah (may Allah be pleased with her) presented a piece of barley bread before the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: "This is the first food your father is eating after three days."
