What should a girl do after her mother's husband attempted to rape her without completing the act? And does this affect his marriage contract with her mother? And must she inform her mother and sisters?

The girl must inform her mother and brothers to prevent the crime from occurring, and she must avoid sitting with this forbidden relative if she does not feel safe from his temptation. The guardian must prevent him, even by disciplinary punishment or imprisonment. She must take all necessary precautions to prevent the indecency from happening.
