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 lo! We accepted your solemn pledge that you would not shed one another's blood, and would not drive one another from your homelands - whereupon you acknowledged it; and thereto you bear witness [even now]. 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 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
