Is it allowed for my 11-year-old son, who recently reverted to Islam, to eat non-Halal chicken in our remote Irish town where Halal options are scarce and costly and also because he has dietary restrictions due to allergies?
I wanted to add that it is very nice of you to take the trouble to look into what he should or should not be eating, and he is fortunate to have a supportive parent. I do sympathize with the dietary restrictions and allergies.
If it is available and affordable, and if you have storage space and can take delivery at home, halal meat can sometimes be purchased online. You may have already looked into that, but just putting it out there!
