حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ عُمَرَ بْنِ مَيْسَرَةَ الْقَوَارِيرِيُّ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، حَدَّثَنَا هِشَامٌ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، حَدَّثَنَا أَبُو سَلَمَةَ، حَدَّثَنَا أَبُو هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ لاَ تُنْكَحُ الأَيِّمُ حَتَّى تُسْتَأْمَرَ وَلاَ تُنْكَحُ الْبِكْرُ حَتَّى تُسْتَأْذَنَ ‏"‏ ‏.‏ قَالُوا يَا رَسُولَ اللَّهِ وَكَيْفَ إِذْنُهَا قَالَ ‏"‏ أَنْ تَسْكُتَ ‏"‏ ‏.‏
