Ayesha reported,

The Prophet ﷺ married me when I was a girl of six. We then traveled to Medina and stayed among Banu Harith bin Khazraj. There I fell ill with a fever, and my hair began to fall out, though it later grew back thickly down to my shoulders.My mother Umm Ruman came to me while I was on a swing with some of my friends. She called out to me, and I went to her, not knowing what she wanted. She took me by the hand and stood me at the door of the house. I was panting heavily, and once my breathing settled a little, she took some water and wiped my face and head with it, then brought me inside.There were some women of the Ansar in the house, and they said, "With goodness and blessing, and with the best of fortune." She handed me over to them, and they prepared me for the occasion. Nothing surprised me more than the Messenger of Allah ﷺ arriving in the morning, and she handed me over to him. I was nine years old that day.

Sahih

حدثني فروة بن أبي المغراء حدثنا علي بن مسهر عن هشام عن أبيه

عن عائشة رضي الله عنها قالت

تزوجني النبي ﷺ وأنا بنت ست سنين فقدمنا المدينة فنزلنا في بني الحارث بن خزرج فوعكت فتمرق شعري فوفى جميمة فأتتني أمي أم رومان وإني لفي أرجوحة ومعي صواحب لي فصرخت بي فأتيتها لا أدري ما تريد بي فأخذت بيدي حتى أوقفتني على باب الدار وإني لأنهج حتى سكن بعض نفسي ثم أخذت شيئا من ماء فمسحت به وجهي ورأسي ثم أدخلتني الدار فإذا نسوة من الأنصار في البيت فقلن على الخير والبركة وعلى خير طائر فأسلمتني إليهن فأصلحن من شأني فلم يرعني إلا رسول الله ﷺ ضحى فأسلمتني إليه وأنا يومئذ بنت تسع سنين
