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 remember We took your covenant (to this effect): Shed no blood amongst you, nor turn out your own people from your homes: and this ye solemnly ratified, and to this ye can bear witness. 84 Yet, here you are, slaying one another and driving some of your own people from their homelands, aiding one another against them, committing sin and aggression; but if they came to you as captives, you would ransom them. Surely their very expulsion was unlawful for you. Do you believe in one part of the Book and deny another part of it? Those of you who act thus shall be rewarded with disgrace in this world and with a severe punishment on the Day of Resurrection. God is never unaware 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
