Judgement Day said:
It seems that you are referring to Aisha. Muhammad married her when she was 9. But the consummation was not until the consent age.
Ok...
FROM THE HADITH OF SAHIH BUKHARI
Bukhari's Hadith is considered authentic by the majority of Sunni Islamic scholars. It is second to the Quran in terms of importance.

From Bukhari vol. 7, #65:
"Narrated Aisha that the prophet wrote the marriage contract with her when she was six years old and he consummated his marriage when she was nine years old. Hisham said: "I have been informed that Aisha remained with the prophet for nine years (i.e. till his death).""
Bukhari vol. 7, #88:
"Narrated Urwa: "The prophet wrote the (marriage contract) with Aisha while she was six years old and consummated his marriage with her while she was nine years old and she remained with him for nine years (i.e. till his death).""
Bukhari vol. 5, #234 says:
"Narrated Aisha: The prophet engaged me when I was a girl of six. We went to Medina and stayed at the home of Harith Kharzraj. Then I got ill and my hair fell down. Later on my hair grew (again) and my mother, Um Ruman, came to me while I was playing in a swing with some of my girl friends. She called me, and I went to her, not knowing what she wanted to do to me. She caught me by the hand and made me stand at the door of the house. I was breathless then, and when my breathing became all right, she took some water and rubbed my face and head with it. Then she took me into the house. There in the house I saw some Ansari women who said, "Best wishes and Allah's blessing and a good luck." Then she entrusted me to them and they prepared me (for the marriage). Unexpectedly Allah's messenger came to me in the forenoon and my mother handed me over to him, and at that time I was a girl of nine years of age."
FROM THE HADITH OF SAHIH MUSLIM VOLUME 2, #3309

FROM THE HISTORY OF TABARI
Tabari wrote the most authentic Islamic history. It covers 39 volumes. Tabari was one of the greatest Islamic scholars and the greatest Islamic Historian.
From Tabari, volume 7, page7:
"....my marriage (to Muhammad) was consummated when I was nine....."
From Tabari, volume 9, page 131
"Then the men and women got up and left. The Messenger of God consummated his marriage with me in my house when I was nine years old. Neither a camel nor a sheep was slaughtered on behalf of me"......(The Prophet) married her three years before the Emigration, when she was seven years old and consummated the marriage when she was nine years old, after he had emigrated to Medina in Shawwal.

FROM THE ENCYCLOPEDIA OF ISLAM, under "Aisha". (pub. by E.J. Brill).
"Some time after the death of Khadija, Khawla suggested to Muhammad that he should marry either Aisha, the 6 year old daughter of his chief follower, or Sawda Zama, a widow of about 30, who had gone as a Muslim to Abyssinia and whose husband had died there. Muhammad is said to have asked her to arrange for him to marry both. It had already been agreed that Aisha should marry Djubayr Mutim, whose father, though still pagan, was friendly to the Muslims. By common consent, however, this agreement was set aside, and Muhammad was betrothed to Aisha.... The marriage was not consummated until some months after the Hidjra, (in April 623, 624). Aisha went to live in an apartment in Muhammad's house, later the mosque of Median. She cannot have been more than ten years old at the time and took her toys to her new home."
From the Muslim book "WOMEN IN ISLAM" by Said Abjullah Seif-Al-Hatimy, published by Islamic Publications in Lahore Pakistan:
"...(Aisha) She was the youngest of his wives. It is said that she was nine years of age when he married her."
