Sahih al-Bukhari, Volume 9, Book 85, Hadith 79 (USC-MSA) ⓘ
Narrated `Aisha: I asked the Prophet, "O Allah's Messenger! Should the women be asked for their consent to their marriage?" He said, "Yes." I said, "A virgin, if asked, feels shy and keeps quiet." He said, "Her silence means her consent."
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ جُرَيْجٍ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنْ أَبِي عَمْرٍو ـ هُوَ ذَكْوَانُ ـ عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ يُسْتَأْمَرُ النِّسَاءُ فِي أَبْضَاعِهِنَّ قَالَ " نَعَمْ ". قُلْتُ فَإِنَّ الْبِكْرَ تُسْتَأْمَرُ فَتَسْتَحِي فَتَسْكُتُ. قَالَ " سُكَاتُهَا إِذْنُهَا ".
