"I came to the Prophet and asked him about the sacrificial meat. I heard him say: 'For a boy, two sheep, and for a girl, one sheep, and it does not matter if they are male or female."' (Using translation from Nasāʾī 4217)  

أَتَيْتُ النَّبِيَّ ﷺ بِالْحُدَيْبِيَةِ أَسْأَلَهُ عَنْ لُحُومِ الْهَدْيِ فَسَمِعْتُهُ يَقُولُ «عَلَى الْغُلَامِ شَاتَانِ وَعَلَى الْجَارِيَةِ شَاةٌ لَا يَضُرُّكُمْ ذُكْرَانًا كَانَتْ أَمْ إِنَاثًا»  

"For a boy, two sheep, and or a girl, one sheep, and it does not matter if they are male or female (Using translation from Nasāʾī 4218)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «عَنِ الْغُلَامِ شَاتَانِ وَعَنِ الْجَارِيَةِ شَاةٌ لَا يَضُرُّكُمْ ذُكْرَانًا كُنَّ أَمْ إِنَاثًا»  

"The Messenger of Allah offered an 'Aqiqah for Al-Hasan and Al-Husain, may Allah be please with them, two rams for each." (Using translation from Nasāʾī 4219)  

«عَقَّ رَسُولُ اللهِ ﷺ عَنِ الْحَسَنِ وَالْحُسَيْنِ بِكَبْشَيْنِ كَبْشَيْنِ»
