Swearing the host will never slaughter an animal and eating from it when slaughtered

Q 2: I swore an oath by Allah that someone should not slaughter the animal. But he disobeyed me and slaughtered it and I ate from it; am I to blame? Should I offer Kaffarah (expiation) for my oath? If any, what is it?

A2: If the reality is as you mentioned, there is no sin on you if you eat from the meat of the slaughtered animal, but you have to offer Kaffarah for breaking your oath, which is to feed ten needy persons from the staple food that you eat, clothe them, or emancipate a believing slave. If you could not do any of these things, you should fast for three days.May Allah grant us success. May Allah's Peace and Blessings be upon our Prophet Muhammad, his family and Companions!
