Messenger of Allah ﷺ said, "It is essential to have the consent of a virgin (for the marriage). I said, "A virgin feels shy." The Prophet; said, "Her silence means her consent." Some people said, "If a man falls in love with an orphan slave girl or a virgin and she refuses (him) and then he makes a trick by bringing two false witnesses to testify that he has married her, and then she attains the age of puberty and agrees to marry him and the judge accepts the false witness and the husband knows that the witnesses were false ones, he may consummate his marriage."  

قَالَ رَسُولُ اللَّهِ ﷺ الْبِكْرُ تُسْتَأْذَنُ قُلْتُ إِنَّ الْبِكْرَ تَسْتَحْيِي قَالَ إِذْنُهَا صُمَاتُهَا وَقَالَ بَعْضُ النَّاسِ إِنْ هَوِيَ رَجُلٌ جَارِيَةً يَتِيمَةً أَوْ بِكْرًا فَأَبَتْ فَاحْتَالَ فَجَاءَ بِشَاهِدَىْ زُورٍ عَلَى أَنَّهُ تَزَوَّجَهَا فَأَدْرَكَتْ فَرَضِيَتِ الْيَتِيمَةُ فَقَبِلَ الْقَاضِي شَهَادَةَ الزُّورِ وَالزَّوْجُ يَعْلَمُ بِبُطْلاَنِ ذَلِكَ حَلَّ لَهُ الْوَطْءُ
