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 know that whatever thing you gain, a fifth of it is for Allah and for the Messenger and for the near of kin and the orphans and the needy and the wayfarer, if you believe in Allah and in that which We revealed to Our servant, on the day of distinction, the day on which the two parties met; and Allah has power over all things.
