Questions for the Muslims who Read This Site

I have a few questions for you guys.

1. Was Mohammad perfect? Do you have any criticisms of him?

Mohammad married Aisha at the age of six, and had sex with her when she was nine years-old.

Volume 5, Book 58, Number 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.

The Koran states that the actions of Mohammad are to be followed for all times.

YUSUFALI: Ye have indeed in the Messenger of Allah a beautiful pattern (of conduct) for any one whose hope is in Allah and the Final Day, and who engages much in the Praise of Allah.

My question to the Muslim men who read this site is:

2.  Would you have sex with a nine year-old?

My question to Muslim men and women who read this site is.

3.  If you had a daughter would you allow her to get married at the age of six, and would you allow a man (or someone of any age) to have sex with her at the age of nine?

Thank you.
