Then, when you [Israelites] killed someone and started to blame one another, God brought to light what you concealed, 72 So We said: "Strike the (body) with a piece of the (heifer)." Thus Allah bringeth the dead to life and showeth you His Signs: Perchance ye may understand. 73 Yet, in spite of this, your hearts only hardened like rocks or even harder, but among rocks are those from which rivers flow; and there are also those which split open and water gushes forth; as well as those that roll down for fear of God. And God is not negligent of all that you do. 74 ۞ Have ye any hope that they will be true to you when a party of them used to listen to the word of Allah, then used to change it, after they had understood it, knowingly? 75 When they meet the faithful, they say, "We are believers." But when alone, they say to each other, "Must you tell them what God has revealed to us? They will only use it to argue against you before your Lord! Have you no sense?" 76 Do they not know that God knows all that they conceal and all that they disclose? 77 And there are among them (Jews) unlettered people, who know not the Book, but they trust upon false desires and they but guess. 78 Then woe to those who write the Book with their own hands, and then say:"This is from Allah," to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby. 79 And they say: "The fire will most certainly not touch us for more than a limited number of days." Say [unto them]: "Have you received a promise from God - for God never breaks His promise - or do you attribute to God something which you cannot know?" 80 Why, they who have earned the wages of sin and are enclosed in error, are people of Hell, where they will abide for ever. 81 But they who believe and do righteous deeds - those are the companions of Paradise; they will abide therein eternally. 82
