lo! those who believed and left their homes and strove with their wealth and their lives for the cause of allah and those who took them in and helped them these are protecting friends one of another. and those who believed but did not leave their homes ye have no duty to protect them till they leave their homes but if they seek help from you in the matter of religion then it is your duty to help except against a folk between whom and you there is a treaty. allah is seer of what ye 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
