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 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 Then there you are killing one another, and expelling a party of you from their habitations, conspiring against them in sin and enmity; and if they come to you as captives, you ransom them; yet their expulsion was forbidden you. What, do you believe in part of the Book, and disbelieve in part? What shall be the recompense of those of you who do that, but degradation in the present life, and on the Day of Resurrection to be returned unto the most terrible of chastisement? And God is not heedless of the things you do. 85 These are they who buy the life of this world for the hereafter, so their chastisement shall not be lightened nor shall they be helped. 86
