If I purchase an item such as chicken from a store, and it is labelled Halal, is it allowed to buy and eat it? Or do I have to go into detail to check further such as call the relevant company for further details?
Bismihi ta'ala
If you have trust (itmi'naan) in the reliability of the label, and its authority, or if it comes from an Islamic country, then you can consider it to be halal, and there is no need to go into detail to check further.
And Allah knows best.
