It is narrated from Sayyida Umm Salama (may Allah be pleased with her), she says: I said, "O Messenger of Allah! What is the ruling for women regarding letting their garments hang down?" The Prophet (peace and blessings be upon him) said: "Let the hem hang down by a handspan." I said, "O Messenger of Allah! Then their feet will become uncovered." The Prophet (peace and blessings be upon him) said: "Let it be a forearm's length, and do not increase more than that."
