"You will find others who wish to obtain security from you and [to] obtain secu- rity from their people. Every time they are returned to [the influence of] disbe- lief, they fall back into it. So if they do not withdraw from you or offer you peace or restrain their hands, then seize them and kill them wherever you over- take them. And those - We have made for you against them a clear authoriza- tion."— Sahih Intl
