Lawful paedophilia in Islam

LAWFUL PAEDOPHILIA IN ISLAM
The Quran has no mentioning of a minimum ages for starting sex with girls. Mohammad and Islam took over the old Arab rule, which was "no rule". Islam builds its rules here on the Quran's lack of rules, and on Muhammad's example, as "Mohammad never sinned" = there is no lower age limit for sex with girl children, and it definitively is lawful and no sin if the girl is at least 9 years old, because that was the age of Mohammad's favourite wife, Aishiah, when he started sex with her - and like said: That child became his favourite wife.
Remember here 5/87, 16/116, 66/1, which all says something like: "Make not lawful the good things which Allah (here via Mohammad's example*) hath made lawful for you".
There never was a 9 years old girl who was sexually mature or mentally adult. We outside Islam classify sex with that young children as rape.
