Actually, if you read the legal aspects of the case everything is indeed according to shari'a as far as I can tell. The mother does not have a right to file this case, and as long as the little girl's husband agrees to wait until puberty to have sex with her then he has fulfilled his obligations. Also, the giving of a daughter in marriage to settle a debt is entirely permissible in Islamic law. The fact that the man is 47 and the girl is eight is not material at all. The girl is a minor and so she has no say in this matter. Her father is her guardian, and then her husband is after the marriage.
Anyway, read it all here:
