Muhammad says that once Hazrat Aisha stayed at the house of Safiyyah Umm Talhah al-Talhat, and she saw that some girls, though having reached puberty, were praying without head coverings. So Hazrat Aisha said, "No girl should pray without a head covering." Once, the Prophet (peace be upon him) came to my house, and at that time there was a girl under my care. The Prophet (peace be upon him) gave me a sheet and said, "Divide it into two parts and distribute it between this girl and the girl under the care of Umm Salamah, because in my opinion, both of them have reached puberty."
