Now that we’ve established that Islam allows husbands to engage in sex with their child-brides, let’s move on to Muhammad and Aisha. The Islamic source materials state that Aisha was 9 when they consummated their marriage.
From the hadith of Bukhari, volume 5, #234
"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."
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).""
From the hadith of Muslim, volume 2, #3309
Aisha reported: Allah’s Messenger married me when I was six years old, and I was admitted to his house at the age of nine….
From the hadith of the Sunan of Abu Dawud, volume 2, #2116
"Aisha said, "The Apostle of Allah married me when I was seven years old." (The narrator Sulaiman said: "Or six years."). "He had intercourse with me when I was 9 years old."
From "The History of 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. She was eighteen years old when he died.
From the Encyclopedia of Islam, under "Aisha":
"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."
SUMMARY OF THE EVIDENCE OF AISHA'S AGE
The above references are just a sample of the Islamic source material statements that Aisha was 9 when her marriage was consummated. Over and over again the great Islamic scholars state that Aisha was 9 when her marriage was consummated. No serious Muslim scholar doubts this. Generally it is only embarrassed Muslims living in the West who challenge her age. For a more in-depth presentation of the evidence of Aisha’s age being 9, see Sam’s article here.
