Abu Mijlaz narrates from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning the saying of Allah Almighty, "Lawful to you is the game of the sea and its food, as provision for you" [Surah al-Ma'idah: 96], that its game is what is caught, and its food means what it casts out.
