Sahih Muslim 3309
A'isha (Allah be pleased with her) reported:
Allah's Messenger (may peace be upon him) married me when I was six years old, and I was admitted to his house at the age of nine.
She further said: We went to Medina and I had an attack of fever for a month, and my hair had come down to the earlobes. Umm Ruman (my mother) came to me and I was at that time on a swing along with my playmates. She called me loudly and I went to her and I did not know what she had wanted of me. She took hold of my hand and took me to the door, and I was saying: Ha, ha (as if I was gasping), until the agitation of my heart was over.
She took me to a house, where had gathered the women of the Ansar. They all blessed me and wished me good luck and said: May you have share in good. She (my mother) entrusted me to them. They washed my head and embellished me and nothing frightened me. Allah's Messenger (, may peace be upon him) came there in the morning, and I was entrusted to him.
