It was narrated that:
Aishah said: "The Messenger of Allah married me when I was six years old. Then we came to Al-Madinah and settled among Banu Harith bin Khazraj. I became ill and my hair fell out, then it grew back and became abundant. My mother Umm Ruman came to me while I was on an Urjuhah with some of my friends, and called for me. I went to her, and I did not know what she wanted. She took me by the hand and made me stand at the door of the house, and I was panting. When I got my breath back, she took some water and wiped my face and head, and led me into the house. There were some woman of the Ansar inside the house, and they said: 'With blessings and good fortune (from Allah).' (My mother) handed me over to them and they tidied me up. And suddenly I saw the Messenger of Allah in the morning. And she handed me over to him and I was at that time, nine years old."
