It was narrated that umm Kurz said:

"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."'

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عُبَيْدِ اللَّهِ، - وَهُوَ ابْنُ أَبِي يَزِيدَ - عَنْ سِبَاعِ بْنِ ثَابِتٍ، عَنْ أُمِّ كُرْزٍ، قَالَتْ أَتَيْتُ النَّبِيَّ ﷺ بِالْحُدَيْبِيَةِ أَسْأَلُهُ عَنْ لُحُومِ الْهَدْىِ فَسَمِعْتُهُ يَقُولُ " عَلَى الْغُلاَمِ شَاتَانِ وَعَلَى الْجَارِيَةِ شَاةٌ لاَ يَضُرُّكُمْ ذُكْرَانًا كُنَّ أَمْ إِنَاثًا " .
