Some scholars have narrated that "If a man penerated a sheep and made her pregnant and she bore a human and that baby grew up and learned his duties and led the prayers of Eid of Al-Adha for the people of the village and then after prayers people slaughtered him as an Eid sacrifice, it is correct for them to do so, because in that case the son is like his mother in decree and because it is correct to sacrifice his mother for Eid, likewise it is correct to sacrifice her son."
