وَعَنْ أَبِي هُرَيْرَةَ رضى الله عنه
أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَا تُنْكَحُ اَلْأَيِّمُ حَتَّى تُسْتَأْمَرَ، وَلَا تُنْكَحُ اَلْبِكْرُ حَتَّى تُسْـتَأْذَنَ «قَالُوا: يَا رَسُولَ اَللَّهِ، وَكَيْفَ إِذْنُهَا ? قَالَ: «أَنْ تَسْكُتَ»
The Messenger of Allah (sallallahu alayhi wa sallam) said: “A previously married woman must not be married till she is consulted, and a virgin must not be married till her consent is asked.” They asked, “O Messenger of Allah, how is her consent indicated?” He replied, “It is by her silence.”.
