Remember that We made a solemn covenant with the children of Israel to this effect: worship none save Allah: be good to your parents, to your relatives, to the orphans and to the helpless; speak aright with the people: establish the Salat and pay the Zakat. But with the exception of a few, you all slid back from it and are paying no heed to it 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
