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 made a covenant with you: You shall not shed your blood and you shall not turn your people out of your cities; then you gave a promise while you witnessed. 84 After this it is ye, the same people, who slay among yourselves, and banish a party of you from their homes; assist (Their enemies) against them, in guilt and rancour; and if they come to you as captives, ye ransom them, though it was not lawful for you to banish them. Then is it only a part of the Book that ye believe in, and do ye reject the rest? but what is the reward for those among you who behave like this but disgrace in this life?- and on the Day of Judgment they shall be consigned to the most grievous penalty. For Allah is not unmindful of what ye do. 85 Those are the ones who have bought the life of this world [in exchange] for the Hereafter, so the punishment will not be lightened for them, nor will they be aided. 86
