They entered upon Hafsah bint 'Abdur-Rahman to ask her about the 'Aqiqah. She informed them that 'Aishah had informed her, that the Messenger of Allah ﷺ ordered them that for a boy, two sheep were sufficient, and for a girl one sheep.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَمَرَهُمْ عَنِ الْغُلاَمِ شَاتَانِ مُكَافِئَتَانِ وَعَنِ الْجَارِيَةِ شَاةٌ قَالَ وَفِي الْبَابِ عَنْ عَلِيٍّ وَأُمِّ كُرْزٍ وَبُرَيْدَةَ وَسَمُرَةَ وَأَبِي هُرَيْرَةَ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو وَأَنَسٍ وَسَلْمَانَ بْنِ عَامِرٍ وَابْنِ عَبَّاسٍ
