Narrated AbuSa'id al-Khudri:

I asked the Apostle of Allah about the embryo. He replied: Eat it if you wish.

Musaddad's version says: we said: Apostle of Allah, we slaughter a she-camel, a cow and a sheep, and we find an embryo in its womb. Shall we throw it away or eat it? He replied: Eat it if you wish for the slaughter of its mother serves its slaughter.
