When a camel is slaughtered, the slaughtering of the mother serves as the slaughtering of what is in her womb, provided its creation is complete and its hair has grown. And when it comes out of its mother's belly, it should be slaughtered so that the blood flows out of its body.
حدثني يحيى عن مالك عن نافع
إذا نحرت الناقة فذكاة ما في بطنها في ذكاتها إذا كان قد تم خلقه ونبت شعره فإذا خرج من بطن أمه ذبح حتى يخرج الدم من جوفه
