They ask you what was made lawful to them, say, "All the good things have been made lawful for you, and what the trained dogs and birds catch; you teach them from what God teaches you." So eat from what they have captured for you and mention God's name upon it, and be aware of God. God is quick in reckoning.
Translation endnotes
[5:4] We should remember God's name or attributes before eating. This remembrance could be verbal or mental and in any language we understand. There is no condition that this remembrance, commonly practiced as uttering Bismillah, should be done when the animals are slaughtered. In the following verse, we are told that the food of the People of the Book is permitted for us. We cannot expect them to remember God's name as we remember and the way we remember.
