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 it is not attributable to a prophet that he should act unfaithfully; and he who acts unfaithfully shall bring that in respect of which he has acted unfaithfully on the day of resurrection; then shall every soul be paid back fully what it has earned, and they shall not be dealt with unjustly.
