"If she is married without her permission, by threat or coercion, then the marriage is not valid. The only exeption is in the case of the father and his daughter who is less than nine years of age.

This is based on the messenger of Allah (peace be upon him) marrying Aisha without her consent when she was less than nine years old, as is stated in authentic Hadith." - Shaikh ibn Baz
