Answered by Shaykh Faraz Rabbani
If I eat something that is Haraam (such as something that contains pork), but learn that it is Haraam AFTER I eat it, do I have to throw it up?
Walaikum assalam wa rahmatullah,
I pray this finds you in the best of health and spirits.
No, you don’t have to vomit it up or anything of the sort, but you should feel bad about it, and repent if it was the result of remissness on your part.
And Allah alone gives success.
