باب فِي الاِسْتِئْمَارِ
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.”

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 ‏"‏ ‏.‏
