Narrated Ibn 'Umar: Narrated Ibn 'Umar (rad): Allah’s Messenger ( صلی اللہ علیہ وسلم ) said: "Two types of dead animals and two types of bloods have been made lawful for us, the two types of dead animals are locusts and fish (seafood), while the two types of bloods are the liver and the spleen". [Reported by Ahmad and Ibn Majah, and this Hadith has some weakness.]
