Marriage Of An Unsound Mind Person
No its not about the sexual impulses of boy but it is a concern of his parents to have somebody who can look after him. I completely agree that it is not ethical rather cruel to find a needy family and get proposal. But people here hardly differentiate between ethical and unethical when its about their interest. Finance is not a problem since they are rich. Thats y i have asked if such marriage if happen is legal or valud in shariah.
If a such a marriage takes place it is still a marriage but unethical one. They can arrange a nurse to take care of him.
