All food was lawful to the children of Israel except that which Israel had forbidden to himself, before the Taurat was revealed. Say: Bring then the Taurat and read it, if you are truthful.

And for those who were Jews We prohibited what We have related to you already, and We did them no injustice, but they were unjust to themselves.

And do not kill any one whom Allah has forbidden, except for a just cause, and whoever is slain unjustly, We have indeed given to his heir authority, so let him not exceed the just limits in slaying; surely he is aided.
