Then, when you [Israelites] killed someone and started to blame one another, God brought to light what you concealed, 72 We said, "Strike [the corpse] with a part of it." Thus God restores the dead to life and shows you His signs, so that you 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 ۞ 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 And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allah has revealed to you so they can argue with you about it before your Lord?" Then will you not reason? 76 Know they (Jews) not that Allah knows what they conceal and what they reveal? 77 And some there are of them that are common folk not knowing the Book, but only fancies and mere conjectures. 78 So woe to those who write the "scripture" with their own hands, then say, "This is from Allah," in order to exchange it for a small price. Woe to them for what their hands have written and woe to them for what they earn. 79 And they say: "The Fire shall not touch us but for a few numbered days:" Say: "Have ye taken a promise from Allah, for He never breaks His promise? or is it that ye say of Allah what ye do not know?" 80 Yes, whoever earns evil and his sin has encompassed him - those are the companions of the Fire; they will abide therein eternally. 81 but those who believe and do good works are the heirs of Paradise; there they shall abide forever. 82
