Sahih al-Bukhari 6970
Narrated Abu Haraira:
Allah's Messenger (ﷺ) 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 (ﷺ) 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."
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا شَيْبَانُ، عَنْ يَحْيَى، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لاَ تُنْكَحُ الأَيِّمُ حَتَّى تُسْتَأْمَرَ، وَلاَ تُنْكَحُ الْبِكْرُ حَتَّى تُسْتَأْذَنَ ‏"‏‏.‏ قَالُوا كَيْفَ إِذْنُهَا قَالَ ‏"‏ أَنْ تَسْكُتَ ‏"‏‏.‏ وَقَالَ بَعْضُ النَّاسِ إِنِ احْتَالَ إِنْسَانٌ بِشَاهِدَىْ زُورٍ عَلَى تَزْوِيجِ امْرَأَةٍ ثَيِّبٍ بِأَمْرِهَا، فَأَثْبَتَ الْقَاضِي نِكَاحَهَا إِيَّاهُ، وَالزَّوْجُ يَعْلَمُ أَنَّهُ لَمْ يَتَزَوَّجْهَا قَطُّ، فَإِنَّهُ يَسَعُهُ هَذَا النِّكَاحُ، وَلاَ بَأْسَ بِالْمُقَامِ لَهُ مَعَهَا‏.‏
