'Neither was it an Arab tradition to give away girls in marriage at an age as young as nine or ten years, nor did the Prophet (pbuh) marry Ayesha (ra) at such a young age. The people of Arabia did not object to this marriage, because it never happened in the manner it has been narrated.' http://www.islamicsupremecouncil.com/ayesha.htm
