Hadith 8:2587
Abu Bakr narrated to us, he said: Yahya ibn Sa’id narrated to us, from Hisham, from al-Hasan, regarding the *badana* (sacrificial camel) that gives birth: He said: He carries its young upon it. If he slaughters it and eats it, he shall slaughter a ram in its place.
حدثنا أبو بكر قال نا يحيى بن سعيد عن هشام عن الحسن في البدنة تنتج قال يحمله عليها فإن ذبحه وأكله ذبح مكانه كبشا
