Child Marriage in Islam (called 'Vani' in Pakistan)

Ibn Abbas reported that a girl came to the Messenger of Allah, and she reported that her father had forced her to marry without her consent. The Messenger of God gave her the choice...(between accepting the marriage or invalidating it) (Ahmad, Hadith no. 2469). another version of the report states that “the girl said: ‘Actually, I accept this marriage, but I wanted to let women know that parents have no right to force a husband on them.’” (Ibn-Majah).
