Sahih al-Bukhari 6968
Narrated Abu Huraira:
The Prophet (ﷺ) said, "A virgin should not be married till she is asked for her consent; and the matron 
should not be married till she is asked whether she agrees to marry or not." It was asked, "O Allah's 
Apostle! How will she (the virgin) express her consent?" He said, "By keeping silent." Some people 
said that if a virgin is not asked for her consent and she is not married, and then a man, by playing a trick 
presents two false witnesses that he has married her with her consent and the judge confirms his 
marriage as a true one, and the husband knows that the witnesses were false ones, then there is no 
harm for him to consummate his marriage with her and the marriage is regarded as valid.
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ لاَ تُنْكَحُ الْبِكْرُ حَتَّى تُسْتَأْذَنَ، وَلاَ الثَّيِّبُ حَتَّى تُسْتَأْمَرَ ‏"‏‏.‏ فَقِيلَ يَا رَسُولَ اللَّهِ كَيْفَ إِذْنُهَا قَالَ ‏"‏ إِذَا سَكَتَتْ ‏"‏‏.‏ وَقَالَ بَعْضُ النَّاسِ إِنْ لَمْ تُسْتَأْذَنِ الْبِكْرُ وَلَمْ تَزَوَّجْ‏.‏ فَاحْتَالَ رَجُلٌ فَأَقَامَ شَاهِدَىْ زُورٍ أَنَّهُ تَزَوَّجَهَا بِرِضَاهَا، فَأَثْبَتَ الْقَاضِي نِكَاحَهَا، وَالزَّوْجُ يَعْلَمُ أَنَّ الشَّهَادَةَ بَاطِلَةٌ، فَلاَ بَأْسَ أَنْ يَطَأَهَا، وَهْوَ تَزْوِيجٌ صَحِيحٌ‏.‏
