I think it is interesting in this thread why you should feel obliged to excuse this marraige of Prophet Mohammed to Aisha. It is known that people married young at that age life expectancy was much shorter. Also girls were given in marraige to seal political alliances.

However just because a girl may reach puberty at an early age it does not neccessarily follow that she is ready and able to take on the role of wife. Physically her body may be preparing her for womanhood but emotionally she may not be ready for all that entails.

It is said that the Prophet Mohammed consummated the marraige when Aisha was nine years old, my today's terms we think too young, but then who can say it may have been common practice. It is also said that Prophet Mohammed married many women and did not consummate the marraige with all of his wives. he had the choice not to consummate the marraige with Aisha but just to love and care for her in a platonic way. he chose not to. Thus leaving muslims with the need to constantly justify his actions in today's world.

Why if Mohammed had so many wives to choose from did he seek the carnel pleasures with a child, but writings show that Aisha herself was ok with this so we can deduce it was a sign of the times they lived in.
Why did Mohammed have so many wives when Allah limited other muslims to having no more than four?
