Surely those who believed and fled (their homes) and struggled hard in Allah’s way with their wealth and their lives, and those who gave shelter and helped -- these are friends one of another. And those who believed and did not flee, you are not responsible for their protection until they flee. And if they seek help from you in the matter of religion, it is your duty to help (them) except against a people between whom and you there is a treaty. And Allah is Seer of what you do.
