What is the ruling on the attempted rape of a nine-year-old girl by her cousin, who is a university student, and what should the family do in this situation, given that they live in the same house?

Attempted rape is forbidden. The girl's father must protect his daughter and cover her (maintain her privacy/honor). The young man's father must advise his son and encourage him to repent and marry. It is preferable for the young man to marry the girl to facilitate chastity and resolve the problem. Disputes between the two families should be avoided.
