This ended up taking a number of posts. Also, I've forgotten a Quran passage, which I have added below. This is from Sura 65 on rules for divorce. Notice below that you can divorce a woman who hasn't menstruated yet ("not had their courses"). Well, how can you divorce a prepubescent woman if you didn't marry a prepubescent woman in the first place? I think the reader can fill in the blanks.
65:4 And (as for) those of your women who have despaired of menstruation, if you have a doubt, their prescribed time shall be three months, and of those too who have not had their courses; and (as for) the pregnant women, their prescribed time is that they lay down their burden; and whoever is careful of (his duty to) Allah He will make easy for him his affair.
When you read about Mohammad's own pedophilia below, you'll understand why he made sure to have the above verse "revealed" to him.
Let's continue with Aisha. The key Hadith sections about Aisha because they are pretty clear (remember when you are reading that Mohammad was 51 when Aisha was 6):
Sahih Muslim Book 008, Number 3310:
'A'isha (Allah be pleased with her) reported: Allah's Apostle (may peace be upon him) married me when I was six years old, and I was admitted to his house when I was nine years old.
Sahih Bukhari Volume 7, Book 62, Number 64
that the Prophet married her when she was six years old and he consummated his marriage when she was nine years old, and then she remained with him for nine years (i.e., till his death).
Sahih Bukhari Volume 7, Book 62, Number 65
that the Prophet married 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)." what you know of the Quran (by heart)'
Sahih Bukhari Volume 7, Book 62, Number 88
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).
Sahih Bukhari 5.236.
Narrated Hisham's father:
Khadija died three years before the Prophet departed to Medina. He stayed there for two years or so and then he married 'Aisha when she was a girl of six years of age, and he consumed that marriage when she was nine years old.
Sahih Bukhari 5.234
The Prophet engaged me when I was a girl of six (years). We went to Medina and stayed at the home of Bani-al-Harith bin Khazraj. 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 Allright, 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 Apostle 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.
And in another Hadith we read.
Sunan Abu-Dawud Book 41, Number 4915, also Number 4916 and Number 4917
Narrated Aisha, Ummul Mu'minin:
The Apostle of Allah (peace_be_upon_him) married me when I was seven or six. When we came to Medina, some women came. according to Bishr's version: Umm Ruman came to me when I was swinging. They took me, made me prepared and decorated me. I was then brought to the Apostle of Allah (peace_be_upon_him), and he took up cohabitation with me when I was nine. She halted me at the door, and I burst into laughter.
Sahih Bukhari Volume 8, Book 73, Number 151
I used to play with the dolls in the presence of the Prophet, and my girl friends also used to play with me. When Allah's Apostle used to enter (my dwelling place) they used to hide themselves, but the Prophet would call them to join and play with me. (The playing with the dolls and similar images is forbidden, but it was allowed for 'Aisha at that time, as she was a little girl, not yet reached the age of puberty.) (Fateh-al-Bari page 143, Vol.13)
So, at the age of nine when the marriage was consummated, she was still playing with dolls and not yet at puberty.
Sahih Muslim Book 008, Number 3311
'A'isha (Allah be pleased with her) reported that Allah's Apostle (may peace be upon him) married her when she was seven years old, and he was taken to his house as a bride when she was nine, and her dolls were with her; and when he (the Holy Prophet) died she was eighteen years old.
In the next post I will discuss common responses from Muslims over the issue of Aisha and why they are false
