And when you slew a soul and then fell out with one another concerning it, Allah made known what you concealed. 72 And We said: Smite him with some of it. Thus Allah bringeth the dead to life and showeth you His portents so that ye may understand. 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 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 Know they (Jews) not that Allah knows what they conceal and what they reveal? 77 And some of them are common (people) and do not know the Book, but only wishful thoughts, and they are only doubters. 78 Woe, then, unto those who write down, with their own hands, [something which they claim to be] divine writ, and then say: "This is from God," in order to acquire a trifling gain thereby; woe, then, unto them for what their hands have written, and woe unto them for all that they may have gained! 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 Indeed, he who earns evil and becomes engrossed in his sin, they are the people of the Fire; in it they shall remain for ever. 81 And those that believe, and do deeds of righteousness -- those are the inhabitants of Paradise; there they shall dwell forever.' 82
