"Say to the Unbelievers, if (now) they desist (from Unbelief), their past would be forgiven them; but if they persist, the punishment of those before them is already (a matter of warning for them). And fight them on until there is no more tumult or oppression, and there prevail Allah altogether and everywhere; but if they cease, verily Allah doth see all that they do. And know that out of all the booty that ye may acquire (in war), a fifth share is assigned to Allah,- and to the Messenger, and to near relatives, orphans, the needy, and the wayfarer,- if ye do believe in Allah and in the revelation We sent down to Our servant on the Day of Testing,- the Day of the meeting of the two forces. For Allah hath power over all things."
