And [recall] when We took the covenant from the Children of Israel, [enjoining upon them], "Do not worship except Allah; and to parents do good and to relatives, orphans, and the needy. And speak to people good [words] and establish prayer and give zakah." Then you turned away, except a few of you, and you were refusing. 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 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 Such are they who buy the life of this world at the price of the Hereafter. Their punishment shall not be lightened for them, nor shall they be helped. 86
