It is not that moulvie's fault , he read in books of ahadees about age of Hazrat Aisha Siddiqa(RA) when she got married to our Holy Prophet (SAW) and when her marriage got consummated. Personally I do not believe in those ahadees and outright reject them.
She wasn't 9 years old she was at least 16 years old and they didn't had sexual relations until she became much older. The hadees on this are weak or not supported well so we cant say that she was 9 or 11 but we can speculate that she might have been 15 or 16 to be married like that otherwise prophet wouldn't have married such a young girl.
