Surely those who believed and fled (their homes) and struggled hard in Allah's way with their property and their souls, and those who gave shelter and helped-- these are guardians of each other; and (as for) those who believed and did not fly, not yours is their guardianship until they fly; and if they seek aid from you in the matter of religion, aid is incumbent on you except against a people between whom and you there is a treaty, and Allah sees what you do.

And he said: You have only taken for yourselves idols besides Allah by way of friendship between you in this world's life, then on the resurrection day some of you shall deny others, and some of you shall curse others, and your abode is the fire, and you shall not have any helpers.
