The sacrificial animal may be male or female
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، أَنْبَأَنَا مُوسَى بْنُ عُبَيْدَةَ، عَنْ إِيَاسِ بْنِ سَلَمَةَ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ كَانَ فِي بُدْنِهِ جَمَلٌ .
It was narrated from Iyas bin Salamah, from his father, that the Prophet (ﷺ) had a (male) camel among his sacrificial animals.
