You should also recall to mind another incident: You slew a man and began to dispute about the murder and accuse one another of it, but Allah had decreed that what you were trying to hide should be disclosed. 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 Thenceforth were your hearts hardened: They became like a rock and even worse in hardness. For among rocks there are some from which rivers gush forth; others there are which when split asunder send forth water; and others which sink for fear of Allah. And Allah is not unmindful of what ye do. 74 ۞ Do you then hope that they will believe in you when some of them have already heard the word of God and then, after having understood it, they knowingly perverted it? 75 On meeting the believers, they would declare belief but to each other they would say, "How would you (against your own interests) tell them (believers) about what God has revealed to you (in the Bible of the truthfulness of the Prophet Muhammad)? They will present it as evidence to prove you wrong before your Lord. Do you not realize it?" 76 Do they not know that Allah knows what they keep secret and what they make known? 77 And there are among them unlettered people who have no real knowledge of the divine writ, [following] only wishful beliefs and depending on nothing but conjecture. 78 Woe to those who write the Book themselves and say, "This is from God," so that they may sell it for a small price! Woe unto them for what they have done and for what they have gained! 79 And they say: Fire shall touch us not save for a few numbered days. Say thou: have ye taken a covenant with Allah, so that Allah shall not fail His covenant? or fabricate ye against Allah that which ye know not 80 Not so; whoso earns evil, and is encompassed by his transgression -- those are the inhabitants of the Fire; there they shall dwell forever. 81 And those that believe, and do deeds of righteousness -- those are the inhabitants of Paradise; there they shall dwell forever.' 82
