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 Remember also that We made another solemn covenant with you: you shall not shed blood among yourselves nor expel one another from your homes. And you confirmed it and you are a witness to it. 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
