Remember, when We made a covenant with the people of Israel and said: "Worship no one but God, and be good to your parents and your kin, and to orphans and the needy, and speak of goodness to men; observe your devotional obligations, and give zakat (the due share of your wealth for the welfare of others)," you went back (on your word), except only a few, and paid no heed. 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
