I came to the Prophet ﷺ at Hudaybiyah to ask him about the meat of the sacrificial offerings, and I heard him say, "For a boy, two sheep, and for a Jariya, one sheep. It does not matter to you whether they are males or females."
أخبرنا قتيبة قال حدثنا سفيان عن عبيد الله وهو ابن أبي يزيد عن سباع بن ثابت
أتيت النبي ﷺ بالحديبية أسأله عن لحوم الهدي فسمعته يقول على الغلام شاتان وعلى الجارية شاة لا يضركم ذكرانا كن أم إناثا
[Its isnad is hasan] Abu Dawud narrated it in the chapter on Sacrifices, Section on Aqiqah, no. 2835, from the hadith of Sufyan bin Uyayna through this route, and he explicitly stated hearing it directly in Humaydi's version, no. 346. It also appears in al-Kubra, no. 4543. Ibn Hibban graded it sahih, no. 1059, as did Hakim and Dhahabi.
