Musannaf Ibn Abi Shayba 3:3416

5793. Abu Usama narrated to us, from Hisham, from Hafsa, from Umm Atiyya, who said: The Messenger of Allah (may Allah bless him and grant him peace) commanded us to bring them out on the day of Fitr and the day of Adha. Umm Atiyya said: We said, "What if one of them does not have a jilbab?" He said: "Let her sister clothe her with her jilbab."
