that thing has got nothing to do with Islam, maybe that retarded thing is in the Pakistani culture,In the UK, the age of consent and for marriage is 16. We see a lot of UK born Pakistani girls sent off to Pakistan in the school holidays to be married off against their will to some old filthy bastard. Their education ends. They sometimes get genitally mutilated at this age too. Poor things. We've recently changed the law to address yet another issue the muslim community can't or won't address itself.
The Islamic Marriage cannot be right and wouldn't be considered as valid without the girl Approval.
