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 Yet ye it is who slay each other and drive out a party of your people from their homes, supporting one another against them by sin and transgression? - and if they came to you as captives ye would ransom them, whereas their expulsion was itself unlawful for you - Believe ye in part of the Scripture and disbelieve ye in part thereof? And what is the reward of those who do so save ignominy in the life of the world, and on the Day of Resurrection they will be consigned to the most grievous doom. For Allah is not unaware 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
