"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»
