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) when We took your covenant (saying): Shed not the blood of your people, nor turn out your own people from their dwellings. Then, (this) you ratified and (to this) you bear witness. 84 But you still kill one another, and you turn a section of your people from their homes, assisting one another against them with guilt and oppression. Yet when they are brought to you as captives you ransom them, although forbidden it was to drive them away. Do you, then, believe a part of the Book and reject a part? There is no other award for them who so act but disgrace in the world, and on the Day of Judgement the severest of punishment; for God is not heedless of all that 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
