Narrated Abu Haraira:
Allah's Apostle said, "A lady slave should not be given in marriage until she is consulted, and a virgin should not be given in marriage until her permission is granted." The people said, "How will she express her permission?" The Prophet said, "By keeping silent (when asked her consent)." Some people said, "If a man, by playing a trick, presents two false witnesses before the judge to testify that he has married a matron with her consent and the judge confirms his marriage, and the husband is sure that he has never married her (before), then such a marriage will be considered as a legal one and he may live with her as husband."
