Then, when you [Israelites] killed someone and started to blame one another, God brought to light what you concealed, 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 ۞ How do you expect them to put their faith in you, when you know that some among them heard the word of God and, having understood, perverted it knowingly? 75 When they meet those who believe in Muhammad, they say, "We also believe in him." But when they meet one another in private, they say, "Have you got no sense that you disclose to them those things which Allah has revealed to you so that they might bring them as a proof against you before your Lord? 76 Do they not know that Allah knows all whatever they hide and whatever they disclose? 77 And some of them are common (people) and do not know the Book, but only wishful thoughts, and they are only doubters. 78 Then woe to those who write the Book with their own hands and then say, "This is from Allah," to purchase with it a little price! Woe to them for what their hands have written and woe to them for that they earn thereby. 79 They have said, "Hell fire will never harm us except for just a few days." (Muhammad), ask them, "Have you made such agreements with God Who never breaks any of His agreements or you just ascribe to Him that which you do not know? 80 Whoever earns evil and becomes engrossed in sin shall be doomed to Hell and abide therein for ever. 81 But those who have faith and work righteousness, they are companions of the Garden: Therein shall they abide (For ever). 82
