And recall what time ye slew a person, then quarrelled among yourselves respecting it, and Allah was to bring out that which ye were hiding. 72 We said: "Apply this [principle] to some of those [cases of unresolved murder]: in this way God saves lives from death and shows you His will, so that you might [learn to] use your reason." 73 Thereafter, your hearts turned as hard as rocks or even harder for some rocks give way to the streams to flow. Water comes out of some rocks when they are torn apart and others tumble down in awe before God. God does not ignore what you do. 74 ۞ Do you then hope that they will believe in you, when some of them have already heard the Word of Allah and knowingly tampered with it, after they understood it! 75 And when they meet those who believe they say: we believe; and when some of them are alone with some others they say speak ye unto them of that which God hath opened unto you so that they may argue therewith against you before your Lord? understand then ye not? 76 Do they not know that Allah knows all whatever they hide and whatever they disclose? 77 And of them are unlettered ones who know not the Book but vain desires; and they do but conjecture. 78 Woe to those who write the scripture with their own hands, and then declare, "This is from God," in order to sell it for a paltry price. Woe to them because of what their own hands have written, and woe to them for what they have earned. 79 And they say, 'The Fire shall not touch us save a number of days.' Say: 'Have you taken with God a covenant? God will not fail in His covenant; or say you things against God of which you know nothing? 80 Whoever earns evil and becomes engrossed in sin shall be doomed to Hell and abide therein for ever. 81 But they who believe and do righteous deeds - those are the companions of Paradise; they will abide therein eternally. 82
