Claim 1: Nonsense, Aisha was playing with dolls and playing on a swing. It specifically says in the hadith that dolls are haram but special allowance was made for Aisha because she was young.

Claim 2: Allah in the Quran allows you to have sex with prepubescent girls in Surah 65:4. Are you saying Muslims that follow this practise ordained by Allah are on a slippery slope?
