"And a proclamation from God and His messenger to all men on the day of the Greater Pilgrimage that God is free from obligation to the idolaters, and so is His messenger. So, if ye repent, it will be better for you; but if ye are averse, then know that ye cannot escape God. Give tidings, O Muhammad, of a painful doom to those who disbelieve.
Excepting those of the idolaters with whom ye have a treaty, and who have since abated nothing of your right nor have supported anyone against you. As for these, fulfil their treaty to them till their term. Lo! God loveth those who keep their duty unto Him."
This is for the people who were against Muhammad and His new religion, after all the harrassment that they have been through.
A few verses after says:
"And of them is he who made a covenant with God saying: If He give us of His bounty we will give alms and become of the righteous.
Yet when He gave them of His bounty, they hoarded it and turned away, averse;
So He hath made the consequence to be hypocrisy in their hearts until the day when they shall meet Him, because they broke their word to God that they promised Him, and because they lied."
Thus the punishment of those who made a covenant with the followers of Muhammad for peace, and then broke that covenant, which lead to the continuous harrassments, pillaging, raping, etc. for the early Muslims, is separation from God for eternity characterised as Fire.
And yet the verse before that says this:
"And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they who are left behind may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware."
This is called defense... when you have people who betrayed you and told your whereabouts so that they can kill you, you really have no choice, do you?
Where is this in the Qur'an?
