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 And when We made a covenant with you, that you shall not shed your blood or turn yourselves out of your dwellings, to this you consented and bore witness. 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 the people who buy the life of this world at the price of the Hereafter: their penalty shall not be lightened nor shall they be helped. 86
