*CONTROVERSY ALERT*
Without going into full discussion on the aspect of Hadith or any other narrative that could be counterproductive, I’d like to look at this from a sociological position. I think when critics of Muhammad’s marriage to A’isha is presented, I think a lot of it has to do with the projection of what we as a society perceive as acceptable and unacceptable.
I think contributing to this are the centuries of paintings and pictures of saints and prophets of the Biblical times presented as grown men and women when in fact historically some of them were younger. For example Mary the mother of Jesus was said to be 14 years old and Joseph, her husband was much older.
But when it comes to renaissance art, Mary is often depicted as a grown mature woman. But I would contest that Mary was probably no mature than your average junior high school girl. We forget that the average life expectancy in those times were less. If I’m not mistaken to live in your 30’s you are or were considered an elder and in your 20’s you may be considered old.
For me, the critique of the prophet Muhammad marrying a 9 year-old girl has more to do with the combination of a dislike for Islam along with the ignorance of human civilization in those times. I am sure in Solomon’s harem, there were plenty of young girls he laid with, but I believe a lot of times our own personal biases influence our way of thinking about the scriptural prophets.
