It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that once we asked the Prophet (peace and blessings be upon him) about the ruling if the calf of a she-camel or a cow dies in its womb. The Prophet (peace and blessings be upon him) said: If you wish, you may eat it, because the slaughtering of its mother is in fact its slaughtering.
