And remember We took a covenant from the Children of Israel (to this effect): Worship none but Allah; treat with kindness your parents and kindred, and orphans and those in need; speak fair to the people; be steadfast in prayer; and practise regular charity. Then did ye turn back, except a few among you, and ye backslide (even now). 83 And when We took compact with you: 'You shall not shed your own blood, neither expel your own from your habitations'; then you confirmed it and yourselves bore witness. 84 Then there you are killing one another, and expelling a party of you from their habitations, conspiring against them in sin and enmity; and if they come to you as captives, you ransom them; yet their expulsion was forbidden you. What, do you believe in part of the Book, and disbelieve in part? What shall be the recompense of those of you who do that, but degradation in the present life, and on the Day of Resurrection to be returned unto the most terrible of chastisement? And God is not heedless of the things 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
