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 when We took compact with you: 'You shall not shed your own blood, neither expel your own from your habitations'; then you confirmed it and yourselves bore witness. 84 And yet, it is you who slay one another and drive some of your own people from their homelands, aiding one another against them in sin and hatred; but if they come to you as captives, you ransom them - although the very [act of] driving them away has been made unlawful to you! Do you, then, believe in some parts of the divine writ and deny the truth of other parts? What, then, could be the reward of those among you who do such things but ignominy in the life of this world and on the Day of Resurrection, commitment to most grievous suffering? For God is not unmindful of what you do. 85 These are the people who bought the worldly life in exchange of the Hereafter – so their punishment will not be lightened, nor will they be helped. 86
