And (remember) when We took a covenant from the Descendants of Israel that, “Do not worship anyone except Allah; and be good to parents, relatives, orphans and the needy, and speak kindly to people and keep the prayer established and pay the charity”; thereafter you retracted, except some of you; and you are those who turn away. 83 We made a covenant with you that you should not shed each other's blood or expel each other from your homeland. You accepted and bore witness to this covenant, 84 Yet you it is who slay your people and turn a party from among you out of their homes, backing each other up against them unlawfully and exceeding the limits; and if they should come to you, as captives you would ransom them-- while their very turning out was unlawful for you. Do you then believe in a part of the Book and disbelieve in the other? What then is the re ward of such among you as do this but disgrace in the life of this world, and on the day of resurrection they shall be sent back to the most grievous chastisement, and Allah is not at all heedless of what you do. 85 Those who have purchased the present life at the price of the world to come -- for them the chastisement shall not be lightened, neither shall they be helped. 86
