Aabis ibn Rabiah reported having asked the Mother of the Faithful Did Allah’s Messenger (SAW) disallow the flesh of the sacrificial animal? She said, No! But few were the people who made a sacrifice. So he liked that those who did not sacrifice should be fed. Indeed, we used to keep aside a trotter and eat it after ten days.’
