verily those who believed and emigrated and strove hard and fought with their property and their lives in the cause of allah as well as those who gave asylum and help these are allies to one another. and as to those who believed but did not emigrate you owe no duty of protection to them until they emigrate but if they seek your help in religion it is your duty to help them except against a people with whom you have a treaty of mutual alliance and allah is the allseer of what you do.
إن الذين آمنوا وهاجروا وجاهدوا بأموالهم وأنفسهم في سبيل الله والذين آووا ونصروا أولئك بعضهم أولياء بعض والذين آمنوا ولم يهاجروا ما لكم من ولايتهم من شيء حتى يهاجروا وإن استنصروكم في الدين فعليكم النصر إلا على قوم بينكم وبينهم ميثاق والله بما تعملون بصير
