Sunan Ibn Majah 3580

Abū Bakr narrated to us; al-Muʿtamir ibn Sulaymān narrated to us, from ʿUbayd Allāh ibn ʿUmar, from Nāfiʿ, from Sulaymān ibn Yasār, from Umm Salamah, who said: The Messenger of Allah, may Allah bless him and grant him peace, was asked, “How much should a woman let her hem trail?” He replied, “A handspan.” I said, “Then it would expose her.” He said, “A cubit; she must not add beyond that.”
