I will not read the other posts at all, but my comment on this would be;
Are these humans?
Are these humans?
No they are not humans, an they are not muslims because as Muhammed Zakir said here in this thread a muslim doesn't rape a Minor
but it seems in this case there is something wrong.Once they bought the child from its father it is not called rape it is called marriage.
Even a father has no right to sell his daughter to anyone. They are kids not vegetables that you can buy in market.
