Hafsah bint Sirin said: Sayyidah Umm Atiyyah (may Allah be pleased with her) narrated to us that they arranged the hair of the head of the daughter of the Messenger of Allah (peace and blessings be upon him) into three braids. (The narrator said:) I asked: Did they undo it and wash it, then make three braids? She said: Yes.
