And the Jews say: The hand of Allah is tied up! Their hands shall be shackled and they shall be cursed for what they say. Nay, both His hands are spread out, He expends as He pleases; and what has been revealed to you from your Lord will certainly make many of them increase in inordinacy and unbelief; and We have put enmity and hatred among them till the day of resurrection; whenever they kindle a fire for war Allah puts it out, and they strive to make mischief in the land; and Allah does not love the mischief-makers.

How can there be an agreement for the idolaters with Allah and with His Messenger; except those with whom you made an agreement at the Sacred Mosque? So as long as they are true to you, be true to them; surely Allah loves those who are careful (of their duty).
