Surah At-Tauba

(This is a declaration of) immunity by Allah and His Apostle towards those of the idolaters with whom you made an agreement.

So go about in the land for four months and know that you cannot weaken Allah and that Allah will bring disgrace to the unbelievers.

And an announcement from Allah and His Apostle to the people on the day of the greater pilgrimage that Allah and His Apostle are free from liability to the idolaters; therefore if you repent, it will be better for you, and if you turn back, then know that you will not weaken Allah; and announce painful punishment to those who disbelieve.

Except those of the idolaters with whom you made an agreement, then they have not failed you in anything and have not backed up any one against you, so fulfill their agreement to the end of their term; surely Allah loves those who are careful (of their duty).

So when the sacred months have passed away, then slay the idolaters wherever you find them, and take them captives and besiege them and lie in wait for them in every ambush, then if they repent and keep up prayer and pay the poor-rate, leave their way free to them; surely Allah is Forgiving, Merciful.
