She wasnt 9. She was 17-19...she needed an extra decade for political clout. It was a political lie that got turned into something worse (pedophilia). Her father was the 2nd caliph (Abu Bakr). He gave her hand to be wed to Mohammed. What father is going to give his 6 year old child to get married to someone? "Mohammed, I have a 6 year old girl...pls marry her, and fuck her when she's 9, pls" c'mon. You have to be reasonable and think of the characters, supporting characters etc as humans, not villainous cut-outs that will fit your childish narratives.
If Mohammed SAAW was a pedophile, all his contemporary enemies would have called him that, all the Christian writers condemning him as a false prophet etc, never once call him a pedo. He is not, you're just infidels and tomorrow you will come up with new slanders and new reasons to not consider him the seal of the prophets.

This is the battle between Aisha and Ali, that made her blurt out the 9 year old stuff (to make her have more clout than her rival, Mohammed's nephew).
btw...if you cared about pedophilia you would have looked into poor rape victim Aisha. Nobody ever does (because they dont care, or they're the actual pedos). If you cared to look at Aisha's biography, you'd realize this wasn't EVER some "me too" victim. This was a LIONNESS. She was alpha boss mode till her death. Never a victim.
