i red your earlier post where you said about the marriage of our prophet........
surely in ancient times the age of girls were quite lower than their husbands.......most prominent reason for that was,the people use to think of girls as burden and used to kill them either before birth or immediately after birth....which is relevant today also in hindus....
you can ask your grandmother what was her age at the time she got married????
regarding in islam one can get married wen one reaches puberty...and aisa did reached puberty before marriage...
further you can go troough the times of india on 26th may...where its gven detail about the girls in india are reaching puberty at the age of 7 also.......
i know you are brainwashed to hate islam and muslims may be even to kill them but atleast talk logicallly...whatever you have written will give chances to some moron muslims to abuse your religion and the outcome would be more hatred among indians.....
its the matters of pakistan better we leave it to them.
