حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَبَانُ، حَدَّثَنَا يَحْيَى، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏"‏ لاَ تُنْكَحُ الثَّيِّبُ حَتَّى تُسْتَأْمَرَ وَلاَ الْبِكْرُ إِلاَّ بِإِذْنِهَا ‏"‏ ‏.‏ قَالُوا يَا رَسُولَ اللَّهِ وَمَا إِذْنُهَا قَالَ ‏"‏ أَنْ تَسْكُتَ ‏"‏ ‏.‏

Abu Hurairah reported the Prophet(ﷺ) as saying “ A woman who has been previously married should not be married until her permission is asked nor should a virgin be married without her permission. “They (the people) asked “What is her permission, Apostle of Allaah(ﷺ)? He replied “it is by her keeping silence.”
