It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) would offer the morning prayer, and when the women finished the prayer and went home, they were wrapped in their large sheets and could not be recognised because of the darkness.
