КОРАН (английский перевод) - 8.72

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.
