those who believe and migrated and fought for the cause of allah with their wealth and their persons and those who sheltered them and helped them shall be guides to each other. and those who believe but have not emigrated you have no guidance towards them till they emigrate. but if they seek your help in the cause of your religion it is your duty to help them except against a nation with whom you have a treaty. allah sees the things 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
