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 We made a covenant with you that you should not shed each other's blood or expel each other from your homeland. You accepted and bore witness to this covenant, 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 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
