Nafi reports that Abdur Rahman bin Abi Hurairah asked Abdullah bin Umar (may Allah be pleased with them both) about an animal which the sea throws out, so Abdullah (may Allah be pleased with him) forbade eating it. Then Abdullah (may Allah be pleased with him) went home and asked for the Book of Allah, and read this verse: "Lawful to you is the game of the sea and its food." Nafi said: Then Abdullah bin Umar (may Allah be pleased with them both) sent me to Abdur Rahman bin Abi Hurairah to tell him that eating that animal is permissible.
