8:56Those of them with whom you made a treaty, but they violate their agreement every time. They are not righteous.

8:72Those who believed, and emigrated, and struggled in God’s cause with their possessions and their persons, and those who provided shelter and support—these are allies of one another. As for those who believed, but did not emigrate, you owe them no protection, until they have emigrated. But if they ask you for help in religion, you must come to their aid, except against a people with whom you have a treaty. God is Seeing of what you do.
