Lo! you are they who will love them while they do not love you, and you believe in the Book (in) the whole of it; and when they meet you they say: We believe, and when they are alone, they bite the ends of their fingers in rage against you. Say: Die in your rage; surely Allah knows what is in the breasts.

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.
