Then when the four months in which you granted security to the polytheists have expired, then announce war on the enemies of Allah wherever they were, and intend them with the siege in their strongholds, and lie in wait for them in their paths, then if they returned from their disbelief and entered Islam and adhered to its laws of establishing the prayer and giving out the Zakat, then leave them, for they have surely become your brothers in Islam, indeed Allah is Forgiving to whoever repented and turned [to Him], Most Merciful to them.
