Sayyidah Aishah (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) married me when I was six years old, and the marriage was consummated when I was nine. She said: I came to Madinah and had a fever for a month, and my hair, which had fallen out, grew back to my shoulders. Then Umm Ruman (may Allah be pleased with her) came to me while I was on a swing with my friends. She called me and I went to her, not knowing why she had called me. She took me by the hand and made me stand at the door of the house, and I was panting until my breath settled. Then she took me into the house, where there were women of the Ansar. They said: 'Ala al-khayri wa al-barakati wa 'ala khayri ta'ir (Upon goodness and blessing, and upon the best of fortune). My mother handed me over to them, and they washed my head and made me ready. Then the Messenger of Allah (peace and blessings be upon him) came in the forenoon, and they handed me over to him (peace and blessings be upon him).
