Those who have iman and have made hijra and done jihad with their wealth and themselves in the Way of Allah, and those who have given refuge and help, they are the friends and protectors of one another. But as for those who have iman but have not made hijra, you are not in any way responsible for their protection until they make hijra. But if they ask you for help in respect of the deen, it is your duty to help them, except against people you have a treaty with. Allah sees what you do.
