Remember, when We made a covenant with the people of Israel and said: "Worship no one but God, and be good to your parents and your kin, and to orphans and the needy, and speak of goodness to men; observe your devotional obligations, and give zakat (the due share of your wealth for the welfare of others)," you went back (on your word), except only a few, and paid no heed. 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 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
