حَدَّثَنَا سُلَيْمَانُ بْنُ عَبْدِ الْحَمِيدِ الْبَهْرَانِيُّ، حَدَّثَنِي يَحْيَى بْنُ صَالِحٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، حَدَّثَنِي عَمْرُو بْنُ مُهَاجِرٍ، عَنْ أَبِيهِ، عَنْ أَسْمَاءَ بِنْتِ يَزِيدَ بْنِ السَّكَنِ الأَنْصَارِيَّةِ، أَنَّهَا طُلِّقَتْ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَلَمْ يَكُنْ لِلْمُطَلَّقَةِ عِدَّةٌ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ حِينَ طُلِّقَتْ أَسْمَاءُ بِالْعِدَّةِ لِلطَّلاَقِ فَكَانَتْ أَوَّلَ مَنْ أُنْزِلَتْ فِيهَا الْعِدَّةُ لِلْمُطَلَّقَاتِ ‏.‏
