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 Muhammad is no more than a messenger; the messengers have already passed away before him; if then he dies or is killed will you turn back upon your heels? And whoever turns back upon his heels!s, he will by no means do harm to Allah in the least and Allah will reward the grateful.
