`Amr ibn al-Muhajir al-Ansari

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 ‏.‏

Amr ibn Muhajir reported on the authority of his father:Asma', daughter of Yazid ibn as-Sakan al-Ansariyyah, was divorced in the time of the Messenger of Allah (ﷺ). No waiting period was prescribed for a divorced woman (at that time). When Asma' was divorced, Allah, the Exalted, sent down the injunction of waiting period for divorce. She is the first of the divorced women about whom the verse relating to waiting period was sent down

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا يَحْيَى بْنُ حَمْزَةَ، عَنْ عَمْرِو بْنِ مُهَاجِرٍ، أَنَّهُ سَمِعَ أَبَاهُ الْمُهَاجِرَ بْنَ أَبِي مُسْلِمٍ، يُحَدِّثُ عَنْ أَسْمَاءَ بِنْتِ يَزِيدَ بْنِ السَّكَنِ، وَكَانَتْ، مَوْلاَتَهُ أَنَّهَا سَمِعَتْ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ ‏ "‏ لاَ تَقْتُلُوا أَوْلاَدَكُمْ سِرًّا فَوَالَّذِي نَفْسِي بِيَدِهِ إِنَّ الْغَيْلَ لَيُدْرِكُ الْفَارِسَ عَلَى ظَهْرِ فَرَسِهِ حَتَّى يَصْرَعَهُ ‏"‏ ‏.‏

It was narrated from Muhajir bin Abu Muslim, from Asma' bint Yazid bin Sakary who was his freed slave womary that:she heard the Messenger of Allah say: "Do not kill your children secretly, for by the One in Whose Hand is my soul, intercourse with a breastfeeding woman catches up with people when they are riding their horses (in battle) and wrestles them to the ground
