Ibn ‘Abbas said that the people of pre-Islamic times used to eat some things and leave others alone, considering them unclean. Then God sent His Prophet and sent down His Book, marking some things lawful and others unlawful; so what He made lawful is lawful, what He made unlawful is unlawful, and what He said nothing about is allowable. And he recited, ''Say, I do not find in what is revealed to me anything forbidden to him who eats it, except carrion or blood..." 1
